3.6 Measurement of the Transfer
Function of Two-Port Networks
(Only for R&S FSH with tracking generator: order
no. 1309.6000.14, 1309.6000.18, 1309.6000.24 or
1309.6000.28.)
For measurements of the gain or attenuation of
four-port devices, the R&S FSH provides a tracking
generator which generates a sinewave signal
exactly at the receive frequency of the R&S FSH.
For measurements on devices under test which
require an external voltage (e.g. power amplifi ers),
connect the supply of a voltage from a suitable
AC power supply to the appropriate BIAS PORT 1
or BIAS PORT 2 input (for R&S FSH models
1309.6000.24 and 1309.6000.28 only).
„
Press the MODE key.
„
Press the NETWORK ANALYZER softkey.
The R&S FSH changes to network analyzer mode
and switches on the tracking generator. Since no
calibration is performed, (UNCAL) is displayed at
the top.
Before calibration, the span you want should be set
because calibration is valid only for the calibrated
span.
„
Press the FREQ key.
„
Using the numeric keys, enter the center
frequency.
