** LIMITED TIME - FREE GLOBAL STANDARD SHIPPING ** This sale is a for a PCMCIA Linear FLASH memory card that is suitable for use in a wide range of equipment. It contains RF Tools but can be erased and used with a wide range of test equipment including the popular HP 8924C/E & Agilent E8285. The data on this particular card is a collection of HP / Agilent communication test set programs for use with their 8920A, 8920B & 8921A Communication Test Sets. Several programs have been modified so they will also work with the popular HP 8924C, HP 8924E & Agilent E8285A test sets. For all options to work, the spectrum analyzer option needs to be fitted to those models which did not have it fitted as standard. Some programs do work without the spectrum analyzer. The photos are screen dumps from one of my HP test sets running the RF Tools suite. You can see the options added. But of coarse, you can also just erase the card and use it to store your own data. Cards that work with these older test sets are getting hard to find! The Programs or Libraries on the card are: FIELD_S A Field-Strength measurement procedure to measures the field strength for a specific user-defined “measurement plan” of up to 22 frequencies that can be measured at up to 22 different locations. Displays minimum, peak, and average power for each frequency at the given location. INTRMOD Intermodulation products are calculated beginning with the first three transmit frequencies (f1, f2, and f3) given by the following formulas: 2nd order product frequencies = f1 ± f2 3rd order product frequencies (2 TX Freqs)= f1 ± 2f2, 2f1 ±f2 3rd order product frequencies(3 TX Freqs)= f1+f2– f3, f3+f1– f2, f2+f3–f1 5th order product frequencies = 2f1 ± 3f2, 3f1 ± 2f2, Then, f1 is checked against f3, f4…f20 Then, f2 is checked against f3, f4…f20 Then, f3 is checked against f4, f5…f20 SCANSWP & SCANDIS These routines turns the test set into a FM radio scanner & only works with models that have a front panel squelch control so does not work on the E8285A. SCANSWP runs a swept scan using values the user entered for start frequency, stop frequency and step frequency. SCANDIS runs a discrete scan of preprogrammed channels. SAVRCL The SAVRCL procedure allows you to save instrument settings in save/recall registers for future use. This allows you to retrieve entire instrument setups instead of having to re-enter the individual settings. RFTOOLS This is a library of the following tests: RFTOOLS - Swept Gain Measures the gain of a device by sweeping it over the specified frequency range. User prompted to enter the frequency range over which the device is to be swept. Requires a 6-dB pad on the antenna and duplex ports. A reference level is obtained by connecting a short calibration cable between the pads on the ports. Next, the test device is added between the calibration cable and one of the pads, and a measurement is made of the additional gain from the reference level. The trace of the device gain over the frequency range swept is displayed. The maximum gain is also displayed on the screen. RFTOOLS - Swept Insertion Loss Similar to the Swept Gain test but measures the loss of a cable or device instead. RFTOOLS - Swept Return Loss Measures the return loss of a cable or device in the swept mode. A SWR bridge and a 6-dB pad are connected to the test set. The pad is used to improve the mismatch between the SWR bridge and the ANT IN port. User prompted to enter the start and stop frequencies. A reference level is measured with a short or open and the return loss is measured with the cable or antenna-under-test. The trace showing return loss over the frequency band selected is displayed on the screen. Measured values for best and worst case return loss are printed at the top of the screen. VSWR can be calculated from the return loss from the VSWR tables included in the instructions. RFTOOLS - AMPS Channel Return Loss This test measures the return loss in a device for discrete cellular AMPS channel frequencies. Test details are provided in the documentation but it will probably be of little use these days. RFTOOLS - Cable Fault This test displays the return loss of a transmission line as a function of the distance down the line. A frequency-swept signal from the DUPLEX OUT port is applied through a resistive power divider to the cable-under-test. Signals reflected from faults in the cable are combined with the DUPLEX OUT signal in the power divider and applied to the ANT IN port. The changing interference of the forward and reflected signals, over the swept frequency band, contains information about the distance to one or more faults. The software uses a Fast Fourier Transform (FFT) to convert the frequency domain into the distance domain. The distance displayed on the test set’s display is the physical distance to the fault with correction for the velocity factor of the cable. RFTOOLS - ERP Calculator This test automatically calculates ERP (effective radiated power), when you enter the data for the following variables: Input Power, Feed Cable Loss & Antenna Gain. This test also allows you the option to enter the ERP and two other variables to automatically calculate the third. (For example, you may enter the values for ERP, Input Power, and Feed Cable Loss. The software will calculate the Antenna Gain). You may select from the following three options for the units of power displayed: dBm, Watts & dBw RFTOOLS - Replot Data Files This is a procedure that allows you to easily retrieve and display plots which were previously stored on an SRAM card. One or two plots may be displayed at one time RFTOOLS - Transfer Stored Data This procedure is used to easily transfer data collection (test results) files from an SRAM card over the serial or HP-IB port. RFTOOLS - SA Self Calibration ON/OFF This procedure is used to turn off the internal spectrum analyser self calibration function. If left on during a RFTOOLS test, it will mess up the results. About HP Memory Cards - 8920, 8921, 8922, 8924 & Agilent E8285 HP used 2 different memory cards for their test sets. The older one is an Epson Card which are almost impossible to locate and even if you do, programming them with anything other than an HP Test set would be tricky. Newer test sets use the more common PCMCIA cards - both SRAM and linear FLASH. This sale is for an Intel Linear Flash card. It will not fit the Epson socket. If you want to use RF Tools and are stuck with a test set that only supports the older Epson cards, it may be possible to upgrade to PCMCIA by changing your A8 memory module. Alternatively you could connect external mass storage to your analyzer via the GBIB bus. The project HPDrive turns a PC into mass storage. If the PC had a PCMCIA slot, then this card could be used. IMPORTANT! The programs on this PCMCIA card will work with the 8920A however the 8920A uses an Epson memory card that is not the same as PCMCIA cards. So if you wish to purchase this for an 8920A, you need to copy the contents from this card to an Epson card as I don't have the ability or the blank Epson cards, to do this for you. Some versions of 8921A may have the Epson card reader which this card will not fit. Older versions of HP 8920A may require a memory upgrade. HP 8920A and HP 8921A Test Sets should have firmware revision A.14.00 or higher to run this software. You will need Option 102, spectrum analyzer and tracking generator for the gain, swept insertion loss, swept return loss, discrete return loss, and cable fault tests. Models of PCMCIA Flash Memory card that you will receive vary with availability. Every card shipped is first tested in an HP 8924C & Agilent E8285A to guarantee compatibility.  Terms Of Sale Goods for sale are as described and pictured.
