The trigger output can operate in several ways: conversion complete, periodic output and comparator output. In addition, the polarity of the trigger output can be specified. CAUTION Precautions should be taken whenever the trigger output is used to coordinate activities among instruments. Static discharges at or near the meter may cause false triggering, causing the trigger output to go active. In TRIG ON CMPLT mode, a pulse is output after each reading has been acquired and completely processed from either channel. When acquiring on one channel, it indicates that the 2832-C is ready to take another reading. The width of this pulse is at least 8 µS. In TRIG AT FREQ mode, a pulse is output at a user defined frequency or rate. Each pulse width is at least 8 µS and the programmable frequency range of the pulses is 0.001 Hz to 1000.0 Hz. In TRIG ON LEVEL mode, each measurement is compared to a programmable trigger level. The units of the trigger level always equal Watts for power detectors. If a measurement is less than the specified value, then the trigger output is inactive. If the measurement exceeds the specified value then the trigger output becomes active. The TRIG ON LEVEL output is a shift in level rather than a pulse. If both channels are sampling when this function is initiated, the time lag between subsequent triggers is less than 700 µsec. If a R/S A or R/S B is initiated twice, then the separation between TTL OUTPUTS is relative to the RUN command initialization, giving a time lag up to one sample period between channel triggers (depending on sample frequency chosen). The polarity of the trigger output is programmable as active high or active low. If the polarity is active high then the output will idle low. If the polarity is active low then the line will idle high. 19

The edge polarity is accessed via the EXT TRIGGER IN menu function and can be set to rising or falling edge triggering. The external trigger affects both channels and, like the R/S key, acts like an acquisition trigger when in SNGL modes and acts like a toggled acquisition gate when in CONT modes. The external trigger pulse width must be ≥200 ns. In DC SNGL mode, the delay from the trigger input going active to the start of the A/D conversion is
