Supplemental Characteristics:
MODULATION RATES: usable from 20 Hz to 100 kHz with degraded
performance.
DETECTORS: +peak, – peak, ±peak/2, peak hold, average (rms
sinewave calibrated), rms.
2. Not to exceed for stated accuracy: 50 Hz to 40 kHz rates with rms detector.
3. Peak residuals must be accounted for in peak readings.
5. For optimum flatness, cables should be terminated with their characteristic
impedance.
6. For peak measurements only: AM accuracy may be affected by distortion generat-
ed by the measuring receiver. In the worst case this distortion can decrease accu-
racy by 0.1% of reading for each 0.1% of distortion.
7. Flatness is the variation in indicated AM depth for constant depth on input signal.
