1) Move the CURSOR to the FRQ field. The following softkeys will be displayed.
⇓(--)
This softkey is the coarse frequency decrement softkey which is used to
decrease the test frequency to the next sequentially lower tenth value after
50 Hz. The frequency points set using this softkey are as follows.
50 Hz 100 Hz 1.0 kHz 10 kHz 100 kHz 200 kHz
↓(-)
This softkey is the fine frequency decrement softkey used to decrease the
test frequency to the next sequentially lower frequency point. The sequential
frequency points which can be set using this softkey are as follows.
50Hz 60Hz 80Hz 100Hz 120Hz 150Hz 200Hz 250Hz
300Hz 400Hz 500Hz 600Hz 800Hz 1kHz 1.2kHz 1.5kHz
2kHz 2.5kHz 3kHz 4kHz 5kHz 6kHz 8kHz 10kz
12kHz 15kHz 20kHz 25kHz 30kHz 40kHz 50kHz 60kHz
80kHz 100kHz 120kHz 150kHz 200kHz
If the input frequency is not the one supported by TH2816B, the TH2816B
will automatically modify to the frequency point which is the nearest higher
point.
↑(+)
This softkey is the fine frequency increment softkey used to increase the
current test frequency to the next sequentially higher frequency point. The
frequency points set using this softkey are the same values as set using
↓(-).
⇑(++)
This softkey is the coarse frequency increment softkey used to increment
the test frequency to the next sequentially higher tenfold value after 50 Hz.
The frequency points set using this softkey are the same as the frequency
points set using ⇓(--).
4.3.1.3 Oscillator Level
TH2816B’s oscillator level can be set as the effective value (RMS value) of a sine
wave of the test frequency from TH2816B's internal oscillator. The oscillator level can
be set from 0 V
rms
to 2.00 V
rms
with a 0.01 V
rms
resolution. The output impedance can
be selected either 30Ω or 100Ω.
Note: The set value of the oscillator voltage level is the value set when the
measurement contacts (UNKNOWN Terminals) are opened.
Front Panel Operation for Setting the Oscillator Level
There are two ways to set the oscillator level. One is to use the softkeys, and the
other is to use the use the numeric entry keys.
Perform the following steps to set the oscillator level.
1) Move the cursor to the LEV field. The following softkeys will be displayed.
⇓(--)
This softkey is the coarse level decrement softkey which is used to decrease
the test signal level by a 0.1 V
rms
step.
↓(-)
This softkey is the fine level decrement softkey which is used to decrease
the test signal level by a 0.01 V
rms
step.
↑(+)
This softkey is the fine level increment softkey which is used to increase the
test signal level by a 0.01 V
rms
step.
