Version 1.6 of the control software for the LA19-13-03 8 GHz VNA is now available. This adds a great deal of additional functionality to the signal generator. It now includes AM and FM modulation, frequency and power sweeps, list sweeps, hop modes and complex sweep. The latter provides phase and amplitude control allowing complex modulation such as QPSK to be emulated. Please see the LA19-13-03 product brochure for further information. Embedded software V1.4 and above needed to support the new control sogftware. Please contact the factory for upgrade information.
