Time gating
Features
Time-selective frequency domain analysis on any input or analog demodulated time-domain data. Inde-
pendent gate delays can be set for each input channel.

Marker functions
Band power
Peak signal track, frequency counter, band power, couple
Can be placed on any time, frequency, or demodulated trace for direct computation of band power, rms
square root (of power), C/N, or C/No, computed within the selected portion of the data.
Occupied bandwidth (OBW)
OBW results
Placed on spectrum traces only to dynamically compute the bandwidth required to provide x% of power
in the band. User selectable from 0 to 100%
Total power in span
Power in OBW
Power ratio (OBW/Span)
OBW lower frequency
OBW higher frequency
OBW
Centroid frequency
Offset frequency (measurement center freq – centroid freq)
Adjacent channel power
Placed on spectrum traces only
User-settable parameters
Center frequency and bandwidth of the carrier channel
Offset frequency and bandwidth of each offset channel
Reference offset allows offset channel to be centered anywhere on screen
ACP results
Pass/fail limits for each offset (applied to both lower and upper result)
Carrier band power
Power in both lower and upper offset bands for each frequency offset
Power in both lower and upper offset bands for each frequency offset, relative to the carrier (ACPR)
Worst case (of the upper and lower offsets) ACPR for each frequency offset
Pass/fail condition relative to user supplied thresholds
