Description
Access Key
AUX CTRL Selects commonly used frequency bands above 18 GHz
and activates the harmonic lock function.
CAL Executes a complete adjustment of the IF system for
optimum measurement accuracy.
MEAS/USER Makes adjacent channel power (ACP) measurements
using time gating techniques.
Switches the automatic IF adjustment on and off.
CAL
When it is on, various IF parameters are adjusted
during retrace to ensure amplitude accuracy within
specifications. If this function is turned off, an A
appears on the left side of the display.
Accesses a menu of signal identification functions or
AUX CTRL
returns the spectrum analyzer from external mixer
mode to its internal frequency coverage.
Recalls the state that existed before preset was
PRESET,
RECALL
pressed or power was turned off.
CAL Displays the first local oscillator frequency
corresponding to the current start frequency.
AUX CTRL Displays the number of the harmonic currently used to
sweep the selected frequency band. Only frequencies
and spans that fall within the frequency band of the
current harmonic may be entered.
Turns the harmonic lock on and off. When it is on, it
AUX CTRL
performs the same function as LOCK HARMONIC.
AUX CTRL Permits manual adjustment of the tracking generator
oscillator using the data keys, the step keys or the
knob.
Reads the difference in amplitude and in frequency (or
AUX CTRL
time when the span equals 0 Hz) and displays these
values.
Activates a single marker and places it at the center of
AUX CTRL,
CAL
the trace.
Accesses softkeys for automatic functions and user
—
defined functions like, power measurements, adjacent
channel power, bandwidth measurements, and FFT
measurements.
MEAS/USER Selects the measurement method that will be used to
make the adjacent channel power measurement.
