Spectrum Analyzer Mode Functions

CHANNEL

BANDWDTH allows the user to enter the channel bandwidth to set up the analyzer when using the measurement functions under

the Power Menu softkey. When the power measurements are first accessed the initial value for channel bandwidth is 16 kHz. If the value is changed, the new value will be saved through an instrument preset or power on. An error message will occur for invalid values of channel bandwidth and channel spacing.

If one of the power measurements is active and the channel bandwidth is changed, with PARAM AUTO selected, then the coupled analyzer settings are immediately updated. If CONT MEXS is also selected, then another sweep is taken and the measured results are updated.

CHANNEL

POWERmeasures the power and power spectral density in the channel bandwidth specified by the user. Two vertical lines

on the display indicate the edges of the channel bandwidth. The measurement can be made on a single sweep or

to continuously update at the end of each sweep. The center frequency, reference level, and channel bandwidth must be set by the user. If PARAM AUTO MAN is selected (AUTO is underlined), other settings will be coupled and set automatically. PARAM AUTO MAN can be selected to manually control all settings by underlining MAN. The measurement stops and the analyzer is returned to its prior state when other functions are activated. The channel power measurement responds like an rms power measurement.
