Key Descriptions
The measurement state parameters that may be
changed include:
• resolution bandwidth
• video bandwidth
• span
• sweep time
• detector mode
• gating parameters
• trigger parameter
• video averaging
Front-panel key access:
Executes a routine that adjusts only the current
ADJ CURRIF STATE
bandwidth state. During this adjustment, the message
IF ADJUST STATUS: <text> appears in the active
function area. Depending on which portion of the IF
system is being adjusted, either AMPLITUDE or a specific
resolution bandwidth (for example, 1 MHz) is displayed
in the message.
Front-panel key access:
AGC
Switches automatic gain control (AGC) ON or OFF.
ON OFF
AGC keeps the volume relatively constant during AM
demodulation. AGC operates only during AM
demodulation and when the frequency span is greater
than 0 Hz.
Front-panel key access:
ALC
For Option 002 only: Activates internal (INT) leveling
INT EXT
or external (EXT) leveling. The external leveling input
is located on the rear panel of the analyzer.
Negative-polarity detectors are supported. External
leveling increases the amplitude accuracy by improving
the effective source match.
Front-panel key access:
Sets the following functions to coupled mode: resolution
ALL
bandwidth, video bandwidth, sweep time, input
attenuator, center-frequency step-size, and units.
