2.3 Measuring Transmissions (Option R&S ZVH-K39)
With option R&S ZVH-K39 (order no. 1309.6830.02) you can perform transmission
measurements (S12).
This measurement example measures the transmission characteristics of a highpass
filter.
Test setup
To measure the transmission, connect the input of the filter to the generator output and
the output of the filter to the RF input.
Setting the frequency span
Before calibrating the R&S ZVH, you should define the frequency range of the filter.
► Press the FREQ/DIST key.
► Press the "Start" softkey.
► Enter 10 MHz as the start frequency.
► Press the "Stop" softkey.
► Enter 100 MHz as the stop frequency.
Calibrating the measurement
For transmission measurements you have to perform a full 2-port calibration to get the
best results.
► Press the CAL key.
► Press the "Full 2-Port" softkey.
The R&S ZVH asks you to connect an "Open", a "Short" and a "Load" to port 1.
► Firmly connect the open, the short and the load to the output end of the cable.
► After each step, proceed with the "Continue" softkey.
After port 1 has been calibrated, the R&S ZVH asks you to connect a "Through" to both
ports.
► Firmly connect the through to both ports of the R&S ZVH.
► Proceed with the "Continue" softkey.
After the calibration, the R&S ZVH shows that it is calibrated by displaying (CAL).
► Reconnect the filter to the ports of the R&S ZVH.
The R&S ZVH now shows the (corrected) characteristics of the highpass filter.
