Making a Measurement
This instrument enables you to make a wide variety of measurements
on digital communications equipment using the
Basic Mode
measurement capabilities. It also has optional measurement
personalites that make measurements based on industry standards.
To set up the instrument to make measurements, you need to:
1. Select a mode or personality which corresponds to a digital
communications format, like cdma2000, W-CDMA, or EDGE. Use
the Basic mode to make measurements of signals with non-standard
formats. After selection of the mode, adjustments to the mode
settings may be made as required.
2. Select a specific measurement to be performed, like ACP, Channel
Power, or EVM, etc. After selection of a measurement, adjustments
to the measurement settings may be made as required.
Depending on Measurement Control settings, the instrument will
begin making the selected measurements. The resulting data will be
shown on the display or available for export.
3. Select a front panel View to display the data from the current
measurement. Depending on the mode and measurement selected,
various graphical and tabular presentations are available.
If you have a problem, and get an error message, see the E4406A VSA
Transmitter Tester Instrument Messages and Functional Tests Guide.
The main keys used in the three steps are shown in the table below.
A setting may be reset at any time, and will be in effect on the next
measurement cycle or View.
