(e) Slope: switch selection of either positive or negative slope of trigger signal.
(f) Coupling: front panel selection of AC, DC, ACF, or ACS.
AC: attenuates signals below approx 20 Hz.
ACF (ac-fast): attenuates signals below approx 15 kHz.
ACS (ac-slow): attenuates signals above approx 30 kHz.
b. Trace Intensification: used when setting up Delayed or Mixed time base. Intensifies that part of Main time base to be expanded to full screen Delayed time base. Rotating Delayed time base sweep switch from Off position activates intensified mode. Front panel screwdriver adjust sets relative intensity of brightened segment.
c. Delayed Time Base: applies to intensified Main, Delayed, and Mixed time base triggering.
(1) Internal: refer to vertical amplifier plug-in specifications.
(2) Automatic: delayed sweep is automatically triggered at end of set time delay.
(3) External: from ac to 50 MHz on signals 0.5V p-p or more, increasing to 100 MHz on signals 1V p-p or more.
(4) Level
INTERNAL: at any point on the vertical waveform displayed.
EXTERNAL: continuously variable from +3V to -3V on either slope of the sync signal; from +30V to -30V in + 10 setting.
(5) Slope: switch selection of either positive or negative slope of trigger signal.
(6) Coupling: Front panel selection of AC, DC ACF, or ACS.
AC: attenuates signals below approx 20 Hz.
ACF (ac-fast): attenuates signals below approx 15 kHz.
ACS (ac-slow): attenuates signals above approx 30 kHz.
(7) Delay (before start of Delayed sweep)
(8) Time: continuously variable from 0.1 µs to 10 a.
(9) Accuracy: ± 1%. Linearity, ± 0.2%. Time jitter is < 0.005% (1 part in 20,000) of maximum delay of each step.
(10) Trigger Output: (at end of Delay time) approx 1.5V with <50 ns rise time from 1000 ohm source resistance.
