5. Lock the module in place using the quarter-turn locking fastener and the rear panel thumbscrew. Hand-
tighten only.
6. Connect the three ribbon cables to the adjacent connector pins in the GPIB board (or adjacent module).
Make sure the connectors are properly seated.
7. If applicable, install each additional module in the slot next to the previous module in the same manner
(go back to step 3).
8. Replace the top cover after all modules are installed.
Note Fully hand-tighten the cover thumbscrew. This engages an internal safety switch. The Electronic Load
will not turn on if the thumbscrews are left loose.
Channel Number
The channel number of a specific module is determined by the location of that module in relation to the GPIB board. For
example, the module next to the GPIB board is always channel number one. Numbering continues sequentially so that the
module furthest from the GPIB board is the highest numbered channel in your system.
Figure 3-3 shows the channel assignments for an Agilent 6050A Electronic Load mainframe containing two Agilent 60502A
single width modules and two Agilent 60504A double-width modules. One channel number is automatically assigned to
each module according to the order in which it was installed in the mainframe. At this time, the maximum number of
available channels is six for Agilent 6050A mainframes, and two for Agilent 6051A mainframes.

Installing The Mainframes
The dimensions of the Agilent 6050A and Agilent 6051A Electronic Loads are specified in Chapter 1. The mainframes have
plastic feet that are shaped to ensure self-alignment when stacked with other Agilent System II instruments. The feet can be
removed for rack mounting.
