R&S RT-ZC20
4. Check that the conductor being measured is not clamped when supplying
power to the R&S RT-ZC20. When power is turned on, a demagnetizing wave-
form is initially applied to the output. This is intentional in the design, and not a
fault.
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.
Figure 3-1: Oscilloscope inputs
The current waveform of the measured conductor is output at a constant rate
(0.1 V/A).
7. Configure the probe connection at the oscilloscope. Make sure to set the fol-
lowing:
● Vertical unit = Ampere
● Coupling = DC
● Termination = 1 MΩ
● Manual Gain = 1 V/A
Alternatively, select "Predefined probe" = R&S RT-ZC20 if this selection is
available on the instrument.
The procedure depends on the used instrument and is described in the oscil-
loscope's user manual. Supported oscilloscopes are listed in the R&S RT-Zxx
data sheet.
8. When disconnecting the output connector, be sure to release the lock before
pulling off the connector. Forcibly pulling the connector without releasing the
lock, or pulling on the cable can damage the terminator.
