5. Turn on the power switch R&S RT-ZA13 probe power supply. Ensure that the front panel power indicator lights. 6. Connect the output connector of the R&S RT-ZC20 to one of the BNC input connectors of the oscilloscope. Turn the collar until it clicks, and check that it is locked securely.
Allice Messtechnik GmbH ® Putting into Operation R&S RT-ZC20 Connecting the Probe to the Oscilloscope Connecting the Probe to the Oscilloscope ► Connect the probe box (1) to the Rohde & Schwarz probe interface of the oscilloscope (2). The probe snaps in when connected properly to the port.
Demagnetizing and Zero Adjustment Risk of circuit damage ● Do not demagnetize while the R&S RT-ZC20 is clamping a conductor to be measured. Demagnetizing causes current to flow into the conductor, which may damage parts in the circuit to be measured.

Allice Messtechnik GmbH ® Putting into Operation R&S RT-ZC20 Connecting the Probe to the DUT ● Immediately after powering on, this device may be subject to an appre- ciable offset drift due to the effect of self-heating. To counteract this, allow the device to warm up for about 30 minutes before carrying out measurements.

Allice Messtechnik GmbH ® Putting into Operation R&S RT-ZC20 Connecting the Probe to the DUT At high frequencies, common mode noise may affect measurements taken on the high voltage side of circuits. If this occurs, reduce the frequency range of the waveform measuring instrument, or clamp onto the low-voltage side of the circuit, as appropriate.
