Preparing to Make Measurements
At initial power up, the analyzer is in spectrum analyzer (SA) mode,
with the Meas Off selected in the
MEASURE menu and the FREQUENCY
Channel
menu displayed.
To access the GSM measurement personality, press the
MODE front
panel key and select the
GSM menu key.
Initial settings
Before making a measurement, make sure the mode setup,
measurement setup, and frequency channel parameters are set to the
appropriate settings. For further information refer to MODE Setup,
FREQUENCY/Channel and Meas Setup in Chapter 5 of the ESA-E
Series Spectrum Analyzers GSM Measurement Personality User’s Guide.
• Resetting all parameters:
To set all instrument parameters (including mode setup and
measurement setup parameters) to factory default values, press the
Preset front panel key. Note that the mode is changed from GSM to
SA when the
Preset front panel key is used. After using Preset you
must use the
MODE key to return to GSM mode.
The
Preset front panel key can also be used to return the instrument
to a set of user preset values.
• Resetting mode setup parameters:
Mode setup parameters apply to all measurements in GSM mode. To
reset them to factory default values, press
Mode Setup then
Restore Mode Setup Defaults.
• Resetting measurement setup parameters:
Measurement setup parameters affect the current measurement
only. To reset them to factory default values (for the current
measurement only), press
Meas Setup then Restore Meas Defaults.
How to make a measurement
GSM measurements are intended to be used as “one button”
measurements. This means that the appropriate measurement can be
selected and run by a single key press once the instrument has been
connected to the equipment to be tested. The measurement is made
automatically using default parameters defined by the selected
standard and the tuning plan.
