Description
Spectral Display Amplitude
Reference
Level Range
and Units Range: +20 dBm to –160 dBm
Units: dBm, dBmV, dBuV, dBV, dBW, V, W
Marker
Power
Accuracy ±1.75 dB, –50 dBm ≤ input ≤ +20 dBm, preamp off
±3.0 dB, –80 dBm ≤ input < –50 dBm, preamp on, above 10 MHz
±3.75 dB, –120 dBm ≤ input < –80 dBm, preamp on, above 10 MHz
Use peak detector for CW signals
Accuracy guaranteed for CW signals and span set to 20 MHz or less
Display
Display
Modes Normal - updates display with each new result
Max Hold - updates displayed point only if new point > old
Min Hold - updates displayed point only if new point < old
Max/Min Hold - displays a vertical bar between Max Hold and Min Hold
Average - displays average of N (speci
fi ed by user) acquisitions
Average is calculated as follows:
Last N values are saved in memory; when a new result is available,
the earliest result of the N stored values is discarded, the new result
is added to the stored values, and a new average is calculated from
the stored values
If the number of results is less than N, then all of the results are
averaged together
Number of
Averages 1 ≤ N ≤ 200
