• MP1 RF Power Meter is a precision instrument within a robust case, facilitating RF systems field testing, adjustment and maintenance. • Operation range 1-2800 MHz , -30 to +10dbm. • 5V power supply via USB connector. • MP1 RF power meter is based on the AD8313 and AD 8307 logarithmic detectors, with a 20 db 1/2Watt input attenuator at each of the two inputs. The RF input power level may range between -40 to 20 dbm for channel A and -50 to 20dbm for channel B. However its accuracy is limited as specified. The power supply is through the USB cable which is used only for +5V, 200mA power supply, without any software interface. SPECIFICATION POWER SUPPLY……………………+5V, 200 mA (USB powered) FREQUENCY RANGE……...............1 to 2800 MHz INPUT POWER LEVEL………..........-30 to 10 dbm RF POWER INPUT B …………1-100 MHz accuracy +/- 0.5 dbm RF POWER INPUT A………… 100-2800 MHz Accuracy: 100-1000 MHz : +/- 0.5 dbm. 1000-2800 MHz : +/- 1.5 dbm. USER A &B Bands 2800-3400 MHz : +/- 2 dbm. 50 Ohm, 1/2 watt, 20db input attenuator at each RF input. • RF inputs A & B : SMA female connectors, power supply : USB connector . • Power levels up to +20 dbm will not damage the inputs, however levels above 10 dbm should be suitably attenuated. • Any DC component within the RF signal is isolated after the 50ohm input attenuator and will load thermally the input attenuators. KEYBOARD MENU key, opens the main menu options. UP key, shifts the menu options UP. DOWN key, shifts the menu options down. SELECT key, activates the displayed menu/submenu option. OPERATION All the functions of the instrument are controlled via the 4 keys keypad. Use the UP and DOWN keys to navigate through the menu and submenu options as described hereafter. To measure power at frequency range 1 to 100 MHz select menu option 3. CHANNEL B POWER. The related calibration factor for this frequency band is selected automatically. To measure power at the frequency range 100 to 2800 MHz first you need to set the related calibration factor for the frequency range of the measurement. To do so select menu option 1. FREQUENCY BAND press the SELECT key to enter to the frequency bands selection submenu and use UP & DOWN keys to navigate to the desired frequency band. Use select to activate the desired frequency band. Then select menu option 2. CHANNEL A POWER to measure the signal at input A. Using inappropriate frequency band will result in wrong measurements. Without any signal at the inputs the displayed values will be at the sensitivity threshold of the logarithmic detectors raised by 20 db. Normally around -40 dbm for channel A and -60 dbm for channel B. Detailed description of the sampling types, the calibration, and the factory reset of the instrument is following. MENU OPTIONS Seven (7) different menu options are available for selection as follows. <MENU OPTIONS SELECT> 1. FREQUENCY BAND 2. CHANNEL A POWER 3. CHANNEL B POWER 4. POWER SUPPLY VOLTAGE 5. CALIBRATION SETUP 6. SAMPLING SETUP 7. FACTORY RESET 1. FREQUENCY BAND. Select the frequency band of the measurement with the up and down keys to set the appropriate calibration factor for the instrument. A discrete pair of calibration factors at 0 and -20 dbm, for each of the 16 frequency bands is stored at the EPROM of the instrument. These factors are user calibrated through the CALIBRATION SETUP menu. The initial 16 pairs of the preset frequency band calibration factors can be easily restored with the FACTORY RESET menu option. Four (4) USER defined bands are included to allow the user to calibrate the instrument at specific frequencies of interest for higher accuracy. In such a case the accuracy is less than +/- 0.25 dbm. The standard and the USER bands A through D are preset for the frequency ranges indicated hereafter. <SET FREQUENCY BAND> 1-100 MHz (used only for Channel B) 100-1000 MHz (used only for Channel A ) 1000-1300 MHz (used only for Channel A ) 1300-1500 MHz (used only for Channel A ) 1500-1650 MHz (used only for Channel A ) 1650-1750 MHz (used only for Channel A ) 1750-1950 MHz (used only for Channel A ) 1950-2200 MHz (used only for Channel A ) 2200-2350 MHz (used only for Channel A ) 2350-2500 MHz (used only for Channel A ) 2500-2650 MHz (used only for Channel A ) 2650-2800 MHz (used only for Channel A ) USER A (2800-3100 MHz) (CHNA only) USER B (3100-3400 MHz) (CHNA only) USER C (100-1000 MHz) (CHNA only) USER D (100-1000 MHz) (CHNA only) USER A & B bands are preset for a range extension up to 3400 MHZ with an accuracy of +/-2 dbm. 2. CHANNEL A POWER activates the 100 to 2800 MHz input. Specified accuracy requires appropriate FREQUENCY BAND selection to set the suitable calibration factor. The default frequency band is the 100-1000 MHz band. There are 3 types of power measurements. Average, Peak and Instantaneous, selected form the SAMPLING SETUP menu. There are 15 frequency bands available for Channel A. CHNA display examples. AVG>CHNA 100-1000MHz (Average power > Channel A -43.949 dbm 50.707 nW 100-1000MHz range) PCK>CHNA 1300-1500MHz (Peak power > Channel A -34.709 dbm 61.564 nW (1300-1500 MHz range ) INS>CHNA 2650-2800MHz (Instantaneous power> CHNA 0.000 dbm 1.000 mW (2650-2800 MHz range ) 3. CHANNEL B POWER activates the 1 to 100 MHz input. Selecting CHNB band the frequency band 1-100MHz is automatically selected. There are 3 types of power measurements. Average, Peak and Instantaneous, selected form the SAMPLING SETUP menu. CHNB display examples. AVG>CHNB 1-100MHz (Average power > Channel B -43.949 dbm 50.707 nW 1-100MHz range) PCK>CHNB 1-100MHz (Peak power > Channel B -34.709 dbm 61.564 nW (1-100 MHz range ) INS>CHNB 1-100MHz (Instantaneous power > CHNB 0.709 dbm 1.564 mW (1-100MHz MHz range ) 4. POWER SUPPLY VOLT. Displays the power supply voltage, normally +5 Volt . 5. CALIBRATION SETUP. The calibration of the instrument is achieved by applying a reference signal with a frequency at the center of the frequency band under calibration, at two different levels, 0 and -20 dbm. This will calibrate the scale of the instrument for the specific frequency band. It is possible to calibrate only one of the two levels. In such a case the other level will remain as it was set during the last calibration. Attention! Prior to perform a successful calibration 4 steps are required: A. Before selecting the calibration setup menu option, it is mandatory to select the desired frequency band to be calibrated, through the FREQUENCY BAND menu option. For example selecting 1 to 100 MHz will calibrate the CHNB unique frequency band. Fail to do so will save the new calibration factors to the wrong frequency band. B. Apply RF signal at the center frequency of the selected frequency band and at the appropriate input CHNA or CHNB. Saving calibration factors for a frequency band while the reference signal is connected to the wrong input channel is a common mistake. C. Set the signal level at 0 dbm. Pay attention to possible cable and connector losses between the reference signal and the instrument. SELECT calibration level 0 dbm from the CALIBRATION SETUP menu option. D. You will be asked to save pressing the SELECT key or to skip saving the calibration data, pressing the MENU key. If you press the SELECT key, the new calibration data will be stored permanently in the instrument EPROM for the selected frequency band and the selected signal level. The ADC (analog to digital converter) level stored, will be indicated on the display for your information. This will be a value around the midrange between the 0 and 1023 ADC levels. Repeat the above procedure for the second level of -20 dbm. To calibrate the second level of the same pair for a frequency band 0 or -20 dbm you may skip setting up again the FREQUENCY BAND menu option. Selecting directly the CALIBRATION SETUP menu option for a second time is sufficient. Four (4) USER defined frequency bands are available only for CHNA. USER A and B bands are preset for the extension frequency ranges mentioned above . USER A (2800-3100 MHz) (CHNA only) USER B (3100-3400 MHz) (CHNA only) USER C (100-1000 MHz) (CHNA only) USER D (100-1000 MHz) (CHNA only) All of the calibration factors for the 16 frequency ranges are stored at related EPROM memory locations. One pair of calibration factor values per frequency band is stored through the above procedure. The user may wish to store on purpose precise calibration factors for a set of up to 15 discrete frequencies for channel A, outside of the ranges indicated, provided that he will prepare a table that will indicate the relation between the displayed and the new calibrated discrete frequencies. For example the 15 CHNA frequency bands of the instrument could be calibrated for 15 UHF radio adjacent channel frequencies, spaced few KHz, to achieve high accuracy measurement for a specific application. Later on the original calibration values could be restored selecting factory restore. 6. SAMPLING SETUP . There are three (3) types of possessing the RF power samples. Average , Peak and Instantaneous. The sampling settings selected under this option apply to both input channels through all the frequency bands. The sampling interval is user defined only for the Average Power type of sampling. Average power is calculated as the average value of an array of 20 samples, taken successively within the sampling interval previously defined in milliseconds. The sampling interval may vary between 20 samples within 5 msec and 20 samples within 1000 milliseconds. The sampling interval is the total time of the sampling period, during which the 20 samples are taken. The preselected value is 25 msec. The Peak Power type of sampling is the max value within an array of 20 samples taken successively during a fixed interval of 25 msec. The peak power increases rapidly but decreases slowly, with a rate of -1 db per second. The Peak Power type of sampling is useful for SSB, DSB and suppressed carrier modulation. The Instantaneous Power type displays one sample every 500 msec. The instantaneous power type is useful for pulsed signals. The Pulse Repetition Frequency (PRF) of a signal and the 500msec interval will result in various power levels displayed alternatively with a rate depended on the timing relation between the PRF and the 500 msec fixed sampling interval. Among those readings there will be a steady highest level which will be the pulse amplitude and the lowest level for the absence of pulse. Intermediate levels will be indicating partial overlapping of the pulse with the ADC sampling period. The ADC sampling period is preset to 200 usec. The measurement will be efficient when the pulse width is at least 200 usec. If Peak or Instantaneous Power is selected the user defined sampling interval is not taken in to account. The predefined fixed sampling intervals are used for these types of sampling. Measuring pulsed signals with the Instantaneous type of sampling or setting the sampling interval high in the Average type of sampling, requires long time of observation at the display, and familiarization with the instrument behavior. 7. FACTORY RESET. Selecting this option you will be asked to confirm or avoid to restore the 16 pairs of calibration factors at their initial factory calibration values. Pressing the SELCT button any user calibration data will be lost permanently and the initial factory calibration factors will be restored. Pressing the MENU button you will return to the main menu without restoring the calibration factors.
