Frequency Conversion Measurements with Vector Network Analyzer R&S®ZVR

Vector Network Analyzer ZVR is able to control two external generators via the IEC/IEEE bus in the frequency conversion mode. This feature allows to make automatic measurements on DUTs with up to two frequency converters. For the measurement of the conversion response over the whole frequency range, one of the two generators must be swept. Since this frequency variation is controlled via the IEC/IEEE bus, the sweep time must be increased (automatically) depending on the used generator. Very short sweep time is possible by the use of a generator SME or SMP and the IEC+TTL remote mode. In this case the generator operates in the frequency list mode triggered by ZVR.
