external power meter, using the “Receiver Power Calibration” dialog) is possible after
completed power calibration of the a-wave.
After the power calibration procedure a system error correction is recommended. Due to
the physical properties of the mm-waves and the 1 mm test set connectors, measure-
ments with external test sets require a special calibration kit for system error correction.
3.6 Measurement
After power calibration and system error correction, the mm-wave measurement can be
performed like any other network analyzer measurement. The "Port Configuration" set-
tings (together with the "Stimulus" settings), determine the sweep range of the converted
signals (i.e. the input and output frequencies at the DUT ports). All measured quantities
(S-parameters, wave quantities, ratios etc.) and other trace settings are available.
The following restrictions hold for measurements in high frequency mode:
●
The measurement is performed at fixed RF source and LO power. No power sweep
is possible.
●
To adjust the actual output power of the converters (e.g. for measuring wave quan-
tities or testing compression effects), use the adjusting knob on top of the converters
(see
chapter 2.4.2, "Output Power Adjusting Screw"
The following example shows a transmission measurement on a through connection in
the frequency range between 10 MHz and 80 GHz.
