selectable frequencies are the same as that of
↑
(+).
↓
(--)
This is a coarse adjustment soft key used to decrease the frequency. The
selectable frequencies are the same as that of
↑
(++).
2)
Use soft keys or numeric keys to select or set frequency. When using numeric
keys to input the required frequency value, the soft key displays the available
frequency units (Hz, kHz and MHz). You can use unit soft key to input unit and
data. When using [ENTER] to input frequency, the default unit is Hz.

Test level
The measurement level of U2829 can be set according to the RMS value of sine
wave signal. The frequency of sine wave signal is the test frequency which is
generated by inner oscillator. You can set measurement voltage or current. The
output impedance of U2829 signal source can be 10
Ω
, 25
Ω
, 50
Ω
or 100
Ω
.When
the test function is DCR, the
FREQ
zone will display “---”.

Note: The measurement current is the output one when the tested
terminal is short, while the measurement voltage is the output one when
the tested terminal is open.

The auto level control function of U2829 can realize the measurement of constant
voltage or current. The auto level control function (ALC) can be set as ON in
<MEAS> page. When the auto level control function is set to ON, “*” will be
displayed following the current level value. Refer to <MEAS> for more
information.
Operation steps for setting test level:
U2829 provides two methods to set the level of test signal source. The first one is
to use soft keys, while the second one is to input data by numeric keys.
1)
Move the cursor to LEVEL, the following soft keys will be displayed.
↑
(+)
This soft key is used to increase the level of test signal source.
↓
(-)
This soft key is used to decrease the level of test signal source.
2)
Soft or numeric keys are used to select or set the test level. When numeric
keys are used to input the desired level, the available units (mV, V, µA, mA
and A) will be displayed in the soft key zone. Users can use these unit keys to
input unit and data. When [ENTER] is used to terminate the input of level, the
default level is V or A.

NOTE: When you need to switch the level between current and voltage,
numeric keys and unit soft keys must be used.
