GENERAL INFORMATION
1-10
Option 11: See Annex B.
Option 12: SINAD measurement
Provides an independent high performance SINAD measurement function.
Measurement range: 50 dB.
Accuracy: ±0.5 dB.
Display
Resolution:
0.01 dB.
Averaging:
User selectable result averaging from 1 to 127 measurements — default setting is 5
measurements.
Over/under range
indication:
Automatic display warning when input signal level is out of range.
Weighting filters: Selectable C-MESS, CCITT P53 weighted measurement filters or unweighted
measurement (50 Hz to 7.0 kHz, 3 dB bandwidth).
Modulation frequency: 1 kHz ±20 Hz notch filter range.
Input signal:
Sensitivity:
50 mV RMS to 3.0 V RMS (250 mV RMS for 50 dB SINAD).
Max. safe input level ±15 V.
Input impedance: 100 k
Ω (nominal).
Input connectivity: SINAD baseband input is via front panel EXT MOD INPUT connector (MOD I/O
connector when Option 7 or 11 is fitted).
Option 100: See Annex C.
