Verifying the Functionality of the Signal Generator
Power On the Signal Generator and Check for Error Messages
This procedure verifies that the signal generator powers up and that the internal instrument check
identifies no errors.
1. Turn on power to the signal generator by pressing the power switch. The green LED will light. Let
the signal generator warm up for one hour.
2. Cycle the power to the signal generator. The green LED should again be lit and the signal generator
performs a check.
3. When the display is lit, check to see if the ERR annunciator is turned on.
4. If the ERR annunciator is turned on, review the error messages in the queue by pressing Utility >
Error Info. The first error message in the queue is shown in the text area of the display. Refer to the
service guide for information about the error message.
If there is more than one error message (each message will be designated as 1 of n), press the
View Next Error Message softkey until you have seen all of the messages.
5. When you have resolved all of the error messages, press Clear Error Queue(s) to delete the messages.
Then restart this procedure at step two.
NOTE For signal generators with Option 1E5, ERROR 514, Reference Oven Cold will occur
whenever the signal generator is first connected to AC line power. The OVEN COLD annunciator
and the ERR annunciator will both turn on. The OVEN COLD annunciator will automatically clear
after approximately 5 minutes. The error queue cannot be cleared, however, until the OVEN COLD
annunciator has turned off.

Removing Option UN3
Use the following procedure to remove Option UN3 as a firmware selection, and to remove the
hardware associated with Option UN3.
Removing Option UN3 in Firmware
1. Preset the signal generator.
2. In the MENUS key group, press the hardkey Utility.
3. In the Utility menu, press the softkey Instrument Adjustments, then select Hardware Options.
The signal generator displays a list of hardware options, and an Xindicates a selected option.
4. Highlight Option UN3, then press the softkey Deselect Item.
This removes the X, indicating that Option UN3 is no longer selected.
5. To disable Option UN3, press the softkey Proceed With Reconfiguration.
6. To verify that you want to reconfigure the signal generator without Option UN3, press the softkey
Confirm Change (Instrument will Reboot).
The signal generator reboots to the preset condition, and removes Option UN3.
Removing Option UN3 Hardware
1. Turn off the line power switch on the signal generator and disconnect the line cord.
2. Loosen the two screws on each handle and remove the two strap handles (Figure 1, page 7, items 1
and 2).
3. Remove the four bottom feet (Figure 1, item 3).
4. Remove the four rear feet (Figure 1, items 4 and 5).
5. Slide the top cover off the signal generator (Figure 1, item 6).
6. Remove the 11 top cover screws and remove the top cover.
7. Disconnect cables W15, W16, W17, and W19 from the A7 baseband generator board (Figure 2, page
7).
NOTE If Option UND is also installed, refer to Figure 3 on page 8 and disconnect W15, W16, W17, W18,
and W24 from the dual arb board (A5).
If Option UN7 is also installed, refer to Figure 4 on page 9 and disconnect A18W1, W21, and W23
from the Bit Error Rate Test board (A6).
8. Remove the baseband generator board (A7).
9. Disconnect cables W3, W4, and W5, and W19 from the A8 data generator board (Figure 5, page 9).
10. Disconnect W18, the rear panel interface ribbon cable, from both the data generator board (A8) and
the rear panel interface board (A17). Discard this older version of W18.
11. Remove the data generator board (A8).

Installing Option UN8 Hardware and Cables
Refer to Figures 6 and 7 on page 11 to assist you in installing the new A7 and A8 assemblies.
NOTE If the signal generator has Option UND installed, you will also need to refer to refer to Figure 3
on page 8.
1. Insert the Board Assy-Generator/1 Meg (A8) into the A14J4 motherboard connector.
2. Insert the Real-Time I/Q Baseband Generator Board (A7) into the A14J3 motherboard connector.
3. Connect W3 (Data) from the front panel to A14P5 on the motherboard.
NOTE If longer cables are required for W3, W4, and W5, use those provided in this upgrade kit.
Using a 9/16-in. socket, remove the shorter cables from the front panel. Resecure with wavey
washer and hex nuts. Torque to 21 in-lb.
4. Connect W4 (Data Clock) from the front panel to A14P6 on the motherboard.
5. Connect W5 (Symbol Sync) from the front panel to A14P7 on the motherboard.
6. Insert the W18 ribbon cable provided in this upgrade kit between the A17 ribbon cable interconnect,
and A8P2
NOTE If Option UND is installed, reconnect W18 to both A8P2 and A5P1.
7. Connect W17 (I Out) to the rear panel to A7P405.
NOTE If Option UND is installed, reconnect W17 to A5J1 instead of A7P405.
