Oscillator Level
Description
The HP 4284A's oscillator level can be set as the eectivevalue
(RMS value) of a sine wave of the test frequency from the
HP 4284A's internal oscillator. You can set either the oscillator
voltage level or the oscillator current level. The output imp edance is
100.
Note
The set value of the oscillator current level is the value set when the
measurement contacts (UNKNOWN Terminals) are shorted together.
The set value of the oscillator voltage level is the value set when the
measurement contacts (UNKNOWN Terminals) are op ened.
When the Option 001 (p ower amplier/DC-bias) isn't installed,
the oscillator voltage level can b e set from 0 V
rms
to 2 V
rms
with a
resolution as listed in Table 3-2, or the oscillator current level can b e
set from 0 A

to 20 mA

with a resolution as listed in Table 3-2.

Note
It is possible to make the option 001 valid or invalid from the MEAS
SETUP page. When the option 001 function is used, the high p ower
