The PW3336-02, PW3336-03, PW3337-02, and PW3337-03 generate voltage output in response to input
from the D/A OUTPUT terminals.
Analog (level) output
Converts the instrument’s measured values into signal levels and outputs them as a DC voltage. The output
voltage is updated in response to display updates (data updates). It is possible to record fluctuations over
extended periods of time by combining this functionality with a data logger or recorder.
Waveform output
Samples the voltage and current input to the instrument at approximately 87.5 kHz, performs D/A conversion,
and outputs them as an instantaneous voltage waveform, instantaneous current waveform, and instanta-
neous power waveform. It is possible to observe equipment rush current and instantaneous power waveforms
by combining this functionality with an oscilloscope or other instrument.
High-speed active power level output
Calculates the active power every cycle for the voltage or current set as the synchronization source, converts
the resulting values to signal levels, and outputs them as a DC voltage. It is possible to observe power con-
sumption and other properties for abruptly fluctuating loads one wave at a time by combining this functionality
with a recorder or other instrument.
3.8 Using D/A Output
When the frequency of input to the set synchronization source is less than 5 Hz, the output update rate for
analog output and high-speed active power level output varies with the frequency of the input to the synchro-
nization 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.
