Each of the modules can either be looped into the SOURCE or MEAS path or simply
bypassed: the transfer switches which are part of each building block, are controlled by
the analyzer firmware.
For the 67 GHz model R&S
ZVAX-TRM67 we have the following limitations:
●
The pulse modulators operate with reduced performance above f
≈
60 GHz.
●
The operation range of the low-noise preamplifiers is limited to 50 GHz.
