Table 28: Trigger (cont.)
Characteristic Description
Instrument Center Frequency 50 MHz
Trigger Output Voltage, nominal
(Output Current < 1 mA)
HIGH: >2.0 V
LOW: <0.4 V
Trigger Output Impedance, nominal 50
Power Trigger Output Position
Timing Uncertainty
±2 sample points (Decimated clock periods, refer to the following table)
This trigger has no specified timing relation to the signal at the RF input. For a given
instrument setup, the delay from the RF input to this trigger output will be the same within
the uncertainty given in this specification. The time delay can be measured for a specific
instrument setup and it will be stable as long as the setup is not changed. If the setup
changes, the delay should be measured again.
Trigger Re-arm Time, minimum (Fast
Frame ON)
10 MHz Acquisition BW: 25 s
40 MHz Acquisition BW (Opt. B40): 10 s
85 MHz Acquisition BW (Opt. B85): 5 s
125 MHz Acquisition BW (Opt. B125): 5 s
165 MHz Acquisition BW (Opt. B16x): 5 s
Trigger Holdoff Time
Acq BW >40 MHz: 5 ns min. to 1000 ms
Acq BW 40 MHz: 20 ns min. to 1000 ms
