TAS 465 EdgeĆType Trigger Sensitivity,
The typical sensitivities are as follows:
o
oup
e
Trigger Source Typical Signal Level for Stable Triggering
Noise Reject 1.2 divisions from DC to 25ĂMHz, inĆ
creasing to 2.2 divisions at 150 MHz.
0.5 division or less will not trigger.
HF REJ 0.30 division from DC to 10 kHz; attenuĆ
ates signals above the upper -3 dB cutĆ
off frequency of 50 kHz.
LF REJ 0.30 division from 100 kHz to 25 MHz,
increasing to 1.0 division at 150 MHz;
attenuates signals below the lower
-3 dB cutoff frequency of 50 kHz.
AC 0.30 division from 350 Hz to 25 MHz,
increasing to 1.0 division at 150 MHz;
attenuates signals below the -3 dB cutĆ
off frequency of 160 Hz.
Typical signal levels for External Triggering are derived by convertĆ
ing divisions to volts, where 1 division equals 100 mV of trigger
signal level.
Lowest Frequency for Successful OperĆ
ation of Set Level to 50%" Function
50 Hz with 1 division.
Holdoff Control Range Increases Main sweep holdoff time by a factor of 10.
