VectorStar™ MS464xB Series Microwave Vector Network Analyzer Programming Manual : Programming the VectorStar Series VNA : Numeric Data Suffix Reference
 
Numeric Data Suffix Reference
Unit suffixes are not required for data parameters, provided the values are scaled for the global default units. The MS4640B SCPI default units are:
Hz (hertz) for frequency-related parameters
s (second) for time-related parameters
m (meter) for distance-related parameters
ohm for impedance-related parameters
dB for power-related parameters
Henry and Farad for reactance-related parameters
For example, the commands below set the MS4640B marker 1 frequency to 3 GHz.
:CALCulate1:MARKer1:X 3000000000
:CALCulate1:MARKer1:X 3.0E9
The following table provides a reference to the I/O parameter types (and the appropriate multiplier) used with the MS4640B VNA.
