There are four frequency bands available to use with the VRTS with 4 GHz Bandwidth, two of which are intended for measurement only.

The following figure shows each of the four instrument bands available to users:



Object simulation is possible using Band 1 and Band 2 only. Measurement is possible in all four bands.

Attempting to use Band 0 or Band 3 for object simulation triggers a warning and causes NI-VRTS to coerce the Enabled property to FALSE on every object, preventing simulation.

You may either manually select a band using the Instrument Center Frequency property in LabVIEW or allow NI-VRTS to make the selection automatically.

The following table defines the instrument center frequency value that corresponds with each band:

Band Instrument Center Frequency
0 77 GHz
1 78 GHz
2 79 GHz
3 80 GHz
