Setting and Using the Measurement Functions R&S FSH
1145.5973.12 4.90 E-10
Vector measurement of transfer function
(only with option R&S FSH-K2)
With vector measurements, the R&S FSH analyzes both magnitude and phase of the receive signal,
thus correcting the influence it has on the measurement result by means of the complex correction
values obtained from the calibration routines with correct phase. Reference is made to the calibration
standards used (through connection and 50 Ω termination).
Compared to scalar measurement, the vector measurement of the transfer function yields higher
measurement accuracy and dynamic range.
Switching on vector measurement:
¾ Press the MEAS key.
¾ Press the MEAS MODE softkey.
¾ Select VECTOR from the menu using the cursor
keys or the rotary knob.
¾ Confirm your choice with the ENTER key or the
MEAS MODE softkey.
Calibrating the measurement:
Before the R&S FSH is calibrated, the desired center frequency and span must be set. If they are set
later, the calibration values are lost and the measurement must be recalibrated.
¾ Press the MEAS key.
¾ Press the TRANSM CAL softkey.
To calibrate the transfer measurement, the R&S FSH
requests that the RF input be connected to the
tracking generator output.
¾ Connect the RF input of the R&S FSH directly to
the tracking generator output without the DUT.
¾ Press the F1 or F2 (CONTINUE) softkey to start
calibration.
¾ By pressing the F4 or F5 (CANCEL) softkey,
calibration can be aborted.
During calibration, the R&S FSH outputs the message
"Calibrating THROUGH, please wait...".
Calibration can be aborted with CANCEL.
