Spectrum Analyzer Mode Functions

MK NOISE ON DFF

MK PAUSE ON OFF

MK READ F T I P

MK TABLE ON OFF

reads out the average noise level, referenced to a 1 Hz noise power bandwidth, at the marker position. If no marker is present, a marker appears at the center of the screen. The root-mean-square noise level, normalized to a 1 Hz noise power bandwidth, is read out. The sample detector is activated.

Front-Panel Key Access (MKRFCTN_)

stops the analyzer sweep at the marker position for the duration of the dwell time. The dwell time can be set from 2 milliseconds to 100 seconds.

Front-Panel Key Access (MKRFCTN]

selects the marker readout to be displayed in signal frequency, sweep time, the inverse of the sweep time, or the period which is the inverse of the frequency. When the instrument is in zero span the frequency type readout cannot be selected.

Front-Panel Key Access m

provides a list of the four available markers which is updated at the end of each sweep or when a marker is used. The marker data can be displayed in different formats. It can be in absolute or delta frequency and amplitude formats. There is also a delta display line format, which can be accessed using the TABLE ADL NRM softkey.

The marker table is not saved with the m and (RECALL) keys.
