Measurement Speed
Measurement speed increases significantly using the meter’s data storage capabilities. Storing data in
memory for later downloading to the controller reduces word serial protocol and protocol conversion
overhead. Up to 128,000 readings can be buffered. The measurement rate depends on several factors,
including controller speed and number of averages. Burst Mode speed does not include bus
communication time. The following lists typical maximum measurement rates for CW power sensors or
Series 80340 Peak Power Sensors.
Individual data points are read immediately after measurement in the Normal Mode. Swift Mode allows
triggering of individual data points, and stores the data in the 58542 memory. Burst Mode also buffers
measurement data: measurement timing of individual data points is controlled by setting the time
interval (0.001 to 5.000 sec) between the data points following a single group burst trigger event.
dB Offset & Relative
Allows both relative readings and offset readings. Power readings can be offset by -99.999
-
+99.999 dB to account for external loss/
gain
Configuration Storage Registers
Up to ten instrument configurations can be stored and recalled from non-volatile memory for fast configuration changes
