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’s block diagram includes three parallel signal paths. One path, the demodulation downconverter,
is primarily used for base station emulation. This frees the measurement downconverter and power detector
from performing functions necessary to maintain an active RF link. 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 link maintenance, one transmitter,
and one receiver measurement 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.
