Hysteresis (Pulse)
Menu Path:
Defines a hysteresis for pulse detection, in dB, relative to the defined threshold. As long as the signal does not exceed the hysteresis, the next threshold crossing is ignored.
You can specify a Hysteresis (dB) offset level within the valid range of 0 to 50 dB.
The measured signal is only considered to contain a valid pulse-on transition if the amplitude first increases above the Pulse Detection Threshold (dBm deciBels referenced to a milliWatt: dB relative to 1 milliwatt dissipated in the nominal input impedance of the analyzer) level.
The measured signal is only considered to contain a valid pulse-off transition if the amplitude subsequently decreases below:
Pulse Detection Threshold (dBm) – Hysteresis (dB) offset level.
For the default case of Hysteresis (dB) = 0 dB, both the pulse-on and pulse-off transition levels are the Pulse Detection Threshold (dBm) level.
By increasing the Hysteresis (dB) greater than 0 dB, you can control and avoid invalid (false) pulse detections which may potentially occur when measuring either noisy or low level pulse signals.
Valid signal pulses are only considered for Pulse Analysis when both a valid pulse-on and subsequent pulse-off transition is detected for that pulse.
- Default value: 0 dB
