Concurrent Measurements
Concurrent Measurements
Description
A number of measurements can be initiated (with the INITiate command) while other measurements are
being made, and the test set will perform as many operations simultaneously as its architecture allows. This
technique is referred to as concurrency. Performing measurements concurrently can greatly improve test
throughput.
Operating Considerations
The test set has three parallel signal paths to improve measurement throughput.
• Demodulation downconverter path.
• Measurement downconverter path.
• Power detector path.
Since measurements are DSP (digital signal processor) based, and there are four A/D converters available to
digitize or “sample” the input signal for analysis by the DSP, the test set will always have the capability to
perform one transmitter measurement, one receiver measurement, and maintain the radio link concurrently.
The test set’s ability to perform multiple transmitter, or multiple receiver tests concurrently will depend on
the availability of resources within the test set and availability of the signal to be tested.
