R&S ZVH

Getting Started

Using a Power Sensor (Option R&S ZVH-K9)

Quick Start Guide 1309.6900.12 - 06

Zeroing the power sensor

To compensate internal offsets of the power meter, it needs to be compensated for
before starting the measurement.

► Press the "Zero" softkey.

The R&S ZVH asks you not to apply any signals to the power sensor while zeroing
is active.

► Disconnect the power sensor from any signal sources.

► Press the "Continue" softkey to start zeroing.

The R&S ZVH starts the zeroing process. It asks you to wait until it is finished.

After zeroing is done, the R&S ZVH outputs the message "Power Sensor Zero OK"
and again shows the power sensor softkey menu.

► Connect the signal under test to the power sensor.

The R&S ZVH shows the measured power level in dBm.

Entering the frequency

To get the best results, also enter the frequency of the signal under test.

► Press the "Freq" softkey.

► Enter the frequency of the signal.

► Confirm the entry with one of the unit keys.

The R&S ZVH transfers the new frequency to the power sensor which then corrects
the measured power readings.
