8.1 Waveform/Analog Output
(Waveform and D/A Output Option)
This instrument’s waveform and D/A output option includes analog output of freely-selected
measured values as well as unmodified voltage and current waveforms.
The analog output can be used to record fluctuations over extended periods of time based on the
data refresh interval.
The waveform output generates output of voltage and current waveforms sampled at a rate
of 2.5 MS/s or 15 MS/s without modification at a rate of 1 MS/s, allowing the waveforms to be
observed through another device, such as an oscilloscope.
Connecting external devices
This section describes how to connect an application-specific device (for example, an oscilloscope,
data logger, or recorder) to the instrument’s D/A output terminal using its D-sub connector.
To ensure safe operation, be sure to turn off the instrument and device before connecting them.
Once the instrument and device have been connected, turn them back on.

Output terminal
The output impedance of each output terminal is
approximately 100
Ω
.
When connecting a recorder, a DMM, or another device,
use a model with high input impedance (1 M
Ω
or more).
See “Specifications of waveform and D/A output
(optional)” (p. 192).
