Option UN3/UN4 to UN8 + UN9
Introduction
The Option UN8 and UN9 Data Generator Assembly Replacement Kit is intended to repair an ESG-D
series signal generator that has a faulty Option UN3 or UN4 data generator assembly. Option UN8 and
UN9 will provide 8M of data pattern RAM, replacing the Option UN3 (Baseband I/Q Generator with 1M of
RAM) or the Option UN4 (Baseband I/Q Generator with 8M of RAM).
The installation process consists of the following basic steps:
1. verifying the functionality of the signal generator
2. removing Option UN3 or UN4
3. installing Option UN8 and UN9
4. installing and verifying new firmware
5. activating Option UN8 and UN9
6. recalibrating and reassembling the signal generator

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 power on 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 or UN4
Use the following procedure to remove Option UN3 or UN4 as a firmware selection and to remove the
hardware associated with Option UN3/UN4.
Removing Option UN3/UN4 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, and then select Hardware Options.
The signal generator displays a list of hardware options, and an X indicates a selected option.
4. Highlight Option UN3 or UN4, then press the softkey Deselect Item.
This removes the X, indicating that Option UN3/UN4 is no longer selected.
5. To disable Option UN3/UN4, press the softkey Proceed with Reconfiguration.
6. To verify that you want to reconfigure the signal generator without Option UN3/UN4, press the softkey
Confirm Change (Instrument will Reboot).
The signal generator reboots to the preset condition, and removes Option UN3/UN4.
Removing Option UN3/UN4 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 on 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 board (Figure 2 on page 7).

NOTE If Option UND is installed, reconnect W15 to A5J3 instead of A7P403. Then connect W24
from A5J4 to A7P403.
10.If Option UN7, bit error rate test board (A6) is installed, refer to Figure 4 on page 8 and reconnect the
following cables:
a. W23 (BER DATA IN) from the rear panel to A6P1
b. W22 (BER CLK IN) from the rear panel to A6P2
c. W21 (BER GATE IN) from the rear panel to A6P3

Installing New Firmware
If required, upgrade the instrument to the latest ESG-B firmware.
Verifying the New Firmware
To verify the new firmware has been downloaded into the signal generator, press Utility >
Instrument Info/Help Mode > Diagnostic Info. The new firmware revision and firmware date should be
displayed under “Instrument Information”.
Activating Options UN8 and UN9
1. Turn on the signal generator and allow it to warm up for at least 30 minutes.
2. Preset the signal generator.
3. Press Utility > Instrument Adjustments > Hardware Options.
4. As when you removed Option UN3/UN4, the signal generator displays a list of hardware options.
Highlight Options UN8 and UN9.
5. Press the Select Item softkey. An X is placed in the Selected column for both Option UN8 and UN9
6. To enable the selected options, press Proceed With Reconfiguration, then press Confirm Change (Instrument
will Reboot).
CAUTION If you enable an option without the required hardware installed, only the menus for that
option are activated; the option does not function.
Internally Recalibrating the Signal Generator
1. Preset the signal generator.
2. Press Utility > Instrument Adjustments > Hardware Options. Confirm that an X appears in the Selected
column for UN8. If it does not, go to step 5 in the procedure above, “Activating Options UN8 and UN9”.
3. Select Calibrate Selected Items > Start Calibration and Store Results.
The calibration takes about five minutes, during which, a message appears indicating that the calibration
is in progress. The message also shows the progress of the calibration, as percent complete. When the
calibration finishes, the message is replaced by the Hardware Options menu.

Reassembling the Signal Generator
Refer to Figure 1 on page 7.
1. Turn off the line power switch on the signal generator and disconnect the line cord.
2. Replace the top cover and torque the 11 screws that secure it to 9 in-lb.
3. Slide the top cover back onto the signal generator (Figure 1, item 6).
4. Replace the four rear feet and torque the four screws to 21 in-lb (Figure 1, items 4 and 5).
