With The P-20A 3 GHz RF PROBE Includes replacement tips P20AX, P20AS, and P20AL Price $179.95 In-circuit RF Measurements have become Elementary DESCRIPTION The P-20A is a PASSIVE 10:1 RF VOLTAGE RF PROBE with a 50 Volt DC BLOCK built in. It has been designed to allow users of RF test equipment to use standard signal tracing techniques. The P-20A makes it possible to conveniently and accurately monitor or inject signals up to 3 GHz into RF circuits without significantly loading or detuning them. The P-20A comes with Interchangeable Ground Clips that adapt to a wide range of applications. Theory of Operation A frequency compensated 450 ohm resistive element is utilized in the RF probe’s design to reduce circuit loading and to give the P-20A a 10:1 VOLTAGE RATIO when connected to a 50 ohm instrument and probing a 50 ohm source. Special construction techniques of the P-20A produce less than 1 pf of stray capacitance at 1 Mhz to minimize the capacitive loading affects on RF circuits. RF instruments require low inductance grounding to make consistent and accurate measurements. TheP-20A’s Interchangeable Ground Clips provide low inductance grounding and the ability to make contact with the circuit’s active RF ground. To prevent false readings or damage to test equipment, an internal DC blocking capacitor ( 50 volts MAX. ) is provided to decouple in-circuit supply voltages. RF Grounding To obtain consistent and accurate RF amplitude measurements PROPER RF grounding is REQUIRED. Measurements from 100 kHz to 1 GHz can be accurately measured by directly grounding the P-20A’s grounding barrel or by using the short pin or flexible ground clip. Frequencies from 1 to 2 GHz will require direct grounding of the P-20A’s grounding barrel or the use of the short pin ground clip. Frequencies from 2 to 3 GHz will require direct grounding of the P-20A’s grounding barrel. See Typical P-20A RF probe response for more information. Ground clips can be changed by grasping the ring portion of the clip and twisting it, while pulling to remove or pushing to assemble. Moderate force may be required. If a good RF ground is out of reach, a 6 inch metal ruler or similar item can often be used to extend the ground to the RF probe. To minimize inductance, it’s better to make direct contact with the grounding barrel of the RF probe. Verification of a low inductance RF ground can be accomplished by slightly changing the P-20A ground contact position while observing that there are no significant changes in readings. CAUTION ! The P-20A’s grounding barrel is a low impedance ground. Avoid Contact with Supply Voltages and Personal Contact if 50 Volts or Higher are present ! RF Voltage Measurements RF Voltage Measurements from 100 kHz to 3 GHz can be made at 7 Volts RMS continuously or up to 35 Volts RMS for one second. The P-20A produces a 10:1 VOLTAGE RATIO when used with instruments, such as RF Volt Meters and RF Detectors while probing a 50 ohm source. RF circuits commonly have or nearly have a 50 ohm impedance and because of this, measurement errors will typically be insignificant for standard signal tracing techniques. Accurate RF Voltage Measurements can be obtained by MULTIPLYING the instrument's reading by 10.05. ( The .05 is the correction factor for the P-20A’s loading characteristics for a 50 ohm source. ) When a source with an impedance other than 50 ohms needs to be accurately measured, use the following equation to obtain the correction factor. TRUE VOLTAGE = ( MEASURED V * 10 ) * L RATIO L RATIO = 1 + ( CIRCUIT IMPEDANCE / 1000 ) RF Power Measurements RF Power Measurements from 100 kHz to 3 GHz can be made up to +30 dBm ( 1.0 watt ) continuously or +44 dBm ( 25 watts ) for one second. The P-20A when used with a Spectrum Analyzer or RF Power Meter can effectively make in-circuit RF Power Measurements with out the need for Complex Calculations. ADD +20 dB to the instrument’s reading if in dBm or MULTIPLY by 100 if using Watts to get the Power Measurement for a 50 ohm source. RF circuits commonly have or nearly have a 50 ohm impedance and because of this, measurement errors will typically be insignificant for standard signal tracing techniques. Pulse Power Measurements up to +56 dBm ( 400 Watts ) can be made, provided the average power level is less than +30 dBm and the Pulse Duration is less than 100 µS. WARNING! An external attenuator should be used between the RF probe and the instrument to prevent the possibility of instrument damage due to excessive peak power. An external DC BLOCK with a adequate voltage rating is also between the RF probe and attenuator to prevent possible damage to measurement equipment if voltages greater than 50 volts are present. When an RF source needs to be measured accurately refer to the "Correction Factor for Loading Effects" chart and the "Power Level Conversion" chart if the source has a impedance other than 50 ohms.
