Maintenance and Performance Checks 5-9
Trigger Gate & Burst
Characteristics
1. Configure all three channels to output a 1.56 MHz Sinewave, 5 Vp-p,
burst count of 10. Set internal trigger generator rate 1 ms. Run *RST
and then:
FREQ 1.56E6;:TRIG:TIM 1E3:;TRIG:CONN 10
2. Use INST:SEL 1|2|3 before the above commands as needed.
3. Perform trigger, gate, and burst tests using Tables 5-6a, 5-6b and 5-
6c.
