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.

8. Connect W16 (Q Out) to the rear panel to A7P404.

NOTE If Option UND is installed, reconnect W16 to A5J2 instead of A7P404.

9. Connect W15 (BASEBAND GENREF IN) to the rear panel to A7P403.

NOTE If Option UND is installed, reconnect W15 to A5J3 instead of A7P403. Then connect W24 from

A5J4 to A7P403.

10. If the 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

d. A18W1 ribbon cable from the A18 board to A6P4

11. Connect the W27 ribbon cable from A7P10 to A8P4.

12. Connect the W19 ribbon cable between A7P300 and A8P3.

13. Remove the W25 (INT Q) cable from between the motherboard connector A14P103 and the

A15 daughterboard, and replace it with the W25 cable provided in this upgrade kit (Figure 7, page

11).

NOTE A14P103 and A14P102 are located under W18.

14. Remove theW26 (INT I) cable from between the motherboard connector A14P102 and the
