4.3 Oscillator settings
The basic setup and operation of the oscillator are described in this section.
■ Setting the output on or off
Use the
OSC
key on the front panel.
The output lamps that are to the right of the
AC/DC ON
key are lit when corresponding AC or DC is
being output.
Pressing the
AC/DC ON
key turns on both the AC output and the DC output.
Pressing the
AC/DC OFF
key turns off both the AC output and the DC output.
Pressing the
AC OFF
turns off the AC output, but the DC output remains on.
It is also possible to turn the output on at the beginning of measurement and have the output turn off
automatically when the measurement is completed. That function is convenient for minimizing the signal
that is applied to the circuit or DUT being measured. For more information, read "
5.4.4 Measurement
synchronization
”.
■ Setting the frequency
The method for setting the oscillator frequency is described here. It is possible to set the frequency over
the range from 10 µHz to 2 MHz with a resolution of 10 µHz. This frequency setting is for performing
measurements with a fixed frequency (SPOT measurement).
