the Execute button for the command to update the instrument. The
functional groups in the Main Panel are explained below.
Parameters
The Parameters group has two parameters for each channel:
Amplitude and Offset. To access the required parameter, click on
the LED or the text next to it to display the required parameter. The
value that is associated with the lit LED is displayed on the digital
display. You can use the dial, keyboard, or the [

} keys to adjust
the readout to the required setting. After you modify the reading,
press Execute to update the 2074 with the new reading.
Function
The Function group is used for selecting between function types.
The 2074 provides four types of waveforms: Standard, Arbitrary,
Sequenced and Modulated. By pressing one of these buttons
output waveform will change to the selected option. The default
function type is Standard. If you want to change standard waveform
parameters, you can select Standard from the Panels bar.
Run Mode
The Run Mode group is used for selecting the active run mode for
the instrument. You can select between continuous, triggered,
gated and burst modes. There is no additional panel associated
with the continuous mode, but if you press one of the other run
mode options, you’ll be able to adjust the trigger parameters from
the Trigger Panel.
Output Control
The Output Control group controls the state of the main outputs and
the sate of the SYNC output. Click on the State buttons to toggle
the outputs on and off.
From this group you also control the position of the SYNC pulse.
The load impedance buttons allow you to adjust the display
amplitude reading to your actual load impedance value. The default
value is 50
Ω
and the output range is calculated in reference to this
value. If your actual load impedance is higher than 50
Ω
and you
increase the load impedance value in this group, the output of the
2074 will display the correct value as is measured on your load
impedance.
Channel
The channel group defines which of the channels is currently being
programmed. Since all four channels have the same controls, it
would have been very crowded to include separate buttons for each
channel and therefore, when you intend to program channel 1
parameters, click on the CH1 button. Likewise if you intend to
program channel 4 parameters, click on the CH4 button.
