Adjusting Passive Probes

R&S

RT-ZP10 passive probes are already pre-compensated to the R&S

RTE

front-end characteristics, and a compensation procedure is not required.

If you use other passive probes, the R&S

RTE allows you to compensate it when

it is connected to the instrument the first time. Compensation matches the probe
cable capacitance to the oscilloscope input capacitance to assure good amplitude
accuracy from DC to upper bandwidth limit frequencies. A poorly compensated
probe reduces the performance of the probe-oscilloscope system and introduces
measurement errors resulting in distorted waveforms and inaccurate results.

1. Connect the BNC connector of the probe to input CH1.

2. Connect the probe's ground connector to the right compensation pin, and the

tip with the left pin.

3. Press AUTOSET.

A square wave appears on the display.

4. Adjust the compensation trimmer of the probe to optimum square wave

response. For details, refer to the documentation of your probe.
