Multiple Source Control Pre-operational Setup
The two sources receive control information from the 37xxxE VNA.
The GPIB address assigned to the external source must be identical to
the address contained in the data directed to the source by the 37xxxE
VNA. Assure source/VNA address compatibility as follows:
Step 1. Install Sources 1 and 2 on the Dedicated GPIB bus.
Step 2. Press the Utility Menu key.
Step 3. Move cursor to GPIB ADDRESSES and press Enter,
when menu U1 (left) appears.
Step 4. When menu GP7 (left) appears, observe that the ad-
dress number is correct. If necessary, use the keypad
to enter a new address.
