3. On the AK40G adapter, a RED LED light indicates power to the adapter. A YELLOW
LED light indicates communication is in process.

Note: Once connected, do not unplug the adapter on either end, before powering down the instrument and the computer first.
Configure GPIB address
1. Press Utility to enter the utility menu, and press Interface to select the interface.
2. Press GPIB and use the rotary knob to set the GPIB address of the generator. The address range is 1 to 30.
3. Be sure that GPIB is highlighted in blue to indicate GPIB as the selected interface for remote communication. Then, select Done.
Note: EasyWave software does not support GPIB interface. It must be used with USB interface only.
Note: All supported remote commands are described in the programming manual. To
obtain a copy, please contact B&K Precision.
Output Configurations
Select Output Setups from the utility menu to configure output parameters.

Output Impedance
The output impedance of the instrument can be switched between 50 Ω and HighZ (high impedance). Select the menu function key corresponding to Load to toggle between the two settings.
Note: If you are connecting directly into an oscilloscope, note that most scopes have 1
MΩ impedance. In this case, it is best to set the output impedance to HighZ to match the load impedance. However if your load impedance is 50 Ω, keep output
impedance set to 50 Ω to match.
Invert Waveform
The main waveform can be inverted by simply selecting Invert from the utility menu. The corresponding menu function key can be pressed to toggle between Normal and Invert output. Inverting a waveform will not change the offset.
Duplicate Channel Parameters
The utility menu has an option that can allow quick copying between channel parameters.
First, press CHCopy option from the menu, and the below menu will display.
Select CH1 -> CH2 to copy channel 1’s parameter settings into channel 2. Likewise, select
CH2 -> CH1 to copy channel 2’s parameter settings into channel 1. After selection, press
Done, and now both channels are identical with the same parameter settings.

To cancel, select Cancel.
Sync Output
Note: Sync output is not available for noise and DC waveforms.
The rear panel has a Sync Out BNC terminal available to provide a synchronization output signal. This output can be enabled and can be setup to provide a sync signal that correlates with channel 1 or channel 2.
To set up, press the Sync option from the utility menu.
Under Channel, use the corresponding menu function key to select CH1 or CH2. This will select the channel the output signal will be synchronized with.
To enable the sync output, select On for the State option.
To disable the sync output, select Off for the State option.
When finished, select Done. To cancel, select Cancel.
Note:
• When waveform is Inverted, the corresponding sync signal does not invert.
• For non-modulated waveform, the sync output reference is the carrier.
• For internal modulating AM, FM, and PM, the sync output reference is the
modulated signal (not the carrier).
• For ASK and FSK, the sync output reference is the keying frequency.
• When sweep is enabled, the sync output becomes TTL level high at the start of
the sweep, and the sync frequency will be the same as the specified sweet time.
• When burst is enabled, the sync output will be TTL level high at the start of the
burst.
• For external gated burst, the sync output follows the external gated signal.
