Chapter 1 Quick Start
To set the output offset voltage
To set the output offset voltage.
At the initial power-on, the generator outputs a cw sine wave at 1 kHz with an offset voltage of 0 V
(into 50
Ω
termination) after the output is turned on. The following steps will show you how to add 1.0
V offset to the output.
1. Press AMPL/OFST button twice or press the double arrow button to exchange the
parameters.
2. Select the digit and enter the desired offset voltage.
Use the left-arrow button to place the cursor under the number 0. Turn the knob to select the desired off-
set voltage. You must observe some restrictions for the magnitude of the offset voltage. The sum of the
offset and peak amplitude can not exceed ±5 volts when terminated with 50
Ω
.

AMPL = 2.500 V
Amplitude and DC Offset Ranges
TEGAM 2411B utilizes unique combinations of the input and output
attenuators for the output amplifier in order to accomplish the optimized
signal attenuation. Therefore, if DC offset is applied to the signal, the
following restrictions must be observed.
Amplitude Range Legal AmDC Offset Limits
1V ~ 10.2V Amp | DC Offset | < 10.4V
100mV ~ 999mV Amp | DC Offset | < 1.00V
10mV ~ 99mV Amp | DC Offset | < 100mV
