Page 13: Connecting The Probe
Handling the probe Connecting the probe Handling the probe The R&S RT-ZC20 can withstand a moderate amount of physical and electrical stress. To avoid damage, treat the probe with care: ● Prevent the probe from receiving mechanical shock. ● This device should be installed and operated indoors only, between 0°C and 40°C (32°F to 104°F) and 80% RH or less. -
Page 14: Connecting The Probe To The Power Supply
Turn off the power switch at the rear of the R&S RT-ZA13 probe power supply. 3. Connect the power cord. 4. Connect the power plug of the R&S RT-ZC20 to the power receptacle of the R&S RT-ZA13 probe power supply. -

BNC connectors, make sure the polarity is correct. To connect the probe: 1. Insert the output connector of the R&S RT-ZC20 into one of the BNC input connectors of the oscilloscope. 2. Turn the collar until it clicks. -
Page 16: Setting Up And Demagnetizing
Setting up and demagnetizing 1. With the waveform measuring instrument input at ground, adjust the waveform to the zero position. 2. Connect the R&S RT-ZC20 current probe to the power supply as described in Chapter 3.2, "Connecting the probe to the power supply", on page 14. -
Page 17: Connecting The Probe To The Dut
® Connecting the probe R&S RT-ZC20 Connecting the probe to the DUT The demagnetizing process takes about one second. During demagnetizing, a demagnetizing waveform is shown on the oscilloscope. The positive and neg- ative components of this waveform may be asymmetrical. - Page 18 ® Connecting the probe R&S RT-ZC20 Connecting the probe to the DUT If the sensor head is not properly closed, accurate measurement is not possi- ble. The current consumption of clamp-on probes depends on the current to be mea- sured. Confirm that the total current consumption of the probes does not exceed the rated output current of the R&S RT-ZA13 probe power supply.

Page 19: Considerations For Measurements
® Connecting the probe R&S RT-ZC20 Considerations for measurements Considerations for measurements Measurements of continuous input current To avoid damage to the probe when doing measurements of continuous input cur- rent, consider the following: ● The maximum continuous input range is based on heat that is internally gen- erated during measurement. - Page 20 ® Connecting the probe R&S RT-ZC20 Considerations for measurements utive maximum current, electric currents in both sides will heat up the sensor and raise the temperature, thereby causing damage to the sensor. Drift, oscillation, and sound ● Immediately after powering on, the probe may be subject to an appreciable offset drift due to the effect of self-heating.
- Page 21 ® Connecting the probe R&S RT-ZC20 Considerations for measurements 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.
