Getting Started
Front Panel Description
2. Control keys set parameters that are used by the measurement in
the current measurement mode.
• FREQUENCY/Channel accesses softkeys that
control the center frequency or channel number.
These parameters apply to all measurements in the
current mode.
• SPAN/X Scale accesses softkeys that control the
horizontal scale in units of frequency, time, symbols
or bits. The parameters in this menu apply only to
the active window in the current measurement. See
page 87 for more detail.
• AMPLITUDE/Y Scale accesses softkeys that control
vertical scale functions in units of dBm, dB, volts,
degrees, or radians. The parameters in this menu
apply only to the active window in the current
measurement. See
page 87 for more detail.
3. Input key The
Input
key accesses softkeys that control the input of
the transmitter tester. These affect all measurements
within the current mode. Note that the internal
50 MHz reference signal and the IF align signal are
used as internal inputs that do not require external
connections. See
page 70 for more detail.
4. View keys
View
keys modify the format of the trace and numeric
data on the display. See page 87 for more detail.
•
View/Trace
accesses softkeys that control the way
results are viewed.
•
Display
accesses softkeys that change the display.
Functions such as limit mask on/off and dots on/off
are available for some measurements.
5. Measure keys are used to select and set up a specific
measurement within the selected application. See page
83 for more detail.
•
MEASURE
accesses softkeys that select and initiate
the various measurements that are specific to the
current mode.
•
Meas Setup
accesses the setup parameters that are
specific to the current measurement.
•
Restart
causes the measurement that is currently in
process to stop, then start again at the beginning
according to the current measurement setup
parameters.
