Click the [Mode] box, and then choose an output type from the list.
PULSE
Outputs a pulse waveform.
PATTERN Outputs a pattern waveform.

Congure the pulse output settings.
Frequency
Allows you to enter a pulse output frequency. (In 0.1 Hz increments)
0.0 Hz to 20000.0 Hz
Duty ratio
Allows you to enter a pulse duty ratio. (In 0.1 percent point increments)
• With the 0% setting, the low-level signal is outputted; with the 100% setting, the high-level signal is
outputted. No pulse is outputted.
• With the 100% setting, the low-level signal is outputted even if the output setting is disabled.
• The output pulse width setting of 1 µs, which can be derived from the frequency and duty ratio settings, may
cause absence of pulses.

Output conguration (Method)
You can congure the output settings.
The ground potential is cross-channel and not insulated.
With the open-collector output setting
• Limit the collector-emitter voltage to 50 V.
• Output signals require a response time of about 5 µs or less to rise from 10% to 90%. (With a load capacity
of 1000 pF and a pull-up resistamce of 1 k
Ω
, values for reference purposes)
TTL
TTL-level output (amplitude: 0-5 V)
OC Open-collector output

Output
Allows you to switch waveform output settings.
The instrument may momentary output a high-level signal at the times of power-on and power-off.
OFF
Does not output any waveform
ON Outputs a waveform

Conrmation of the setting
After nishing the setting, click
[Send setting]
.
The instrument conrms the settings and outputs a waveform.
Conguring the pattern output settings
Pattern number
Enter an pattern number.
• When no output is enabled, the instrument outputs the pattern signal registered rst.
• Turning off the instrument clears pattern data sets. After turning on the instrument, re-register pattern data
set.

Pattern reproducing frequency
Enter a clock frequency of pulse pattern. (In 10 Hz increments)
• Settable clock period range: 0 to 0.1 seconds
• You can freely specify the clock cycle as long as it falls into the above-mentioned range. The cycle of the
actually outputted waveform becomes the nearest value among the reciprocals of settable frequencies.
0 Hz to 120000 Hz
Output conguration
Choose an output status.
