3.7 Using D/A Output
85
The PW3335-02 and PW3335-04 generate voltage output in response to input from the D/A output terminals.
Level (analog) output
Converts the instrument’s measured values into signal levels and outputs a DC voltage. The output voltage is
updated in response to display updates (data updates: approximately every 200 ms). It is possible to record
fluctuations over extended periods of time by combining this functionality with a data logger or recorder.
High-speed level output
Generates level (analog) output for each cycle of the input voltage and input current. Additionally, it is possible
to generate level output for the active power calculated for each cycle of the voltage or current that has been
set as the synchronization source. It is possible to observe power consumption and other properties for
abruptly fluctuating loads one wave at a time by combining this functionality with a recorder or other instru-
ment.
Waveform output
Samples the voltage and current input to the instrument at approximately 700 kHz, performs D/A conversion,
and outputs an instantaneous voltage waveform, instantaneous current waveform, and instantaneous power
waveform. It is possible to observe equipment rush current and instantaneous power waveforms by combin-
ing this functionality with an oscilloscope or other instrument.
3.7 Using D/A Output
When the frequency of input to the set synchronization source is less than 5 Hz, the output update rate for
level output and high-speed level output varies with the frequency of the input to the synchronization source.
Example: If the frequency of input to the synchronization source is 0.8 Hz, the output update rate will be
1/0.8 = 1.25 sec.
