Verify Proper Installation of Option 602

1. Turn the signal generator on.

2. Check that Option 602 is installed by pressing

Utility > Instrument Info/Help Mode > Options Info.

3. Perform the “Checking Signal Generator Functionality” procedure, as described on page 5.

4. Verify that the Baseband Generator self-tests all pass.

Re-Assemble the Signal Generator

Refer to Figure 1.

1. Reinstall the inner and outer instrument covers by reversing the order for removal.

2. Torque all T-10 screws to 9 in-lbs.

3. Torque all T-15 and T-20 screws to 21 in-lbs.

4. Attach the Option 602 label to the rear panel, near the original serial number label.

5. Attach the Digital Bus label over “DIG I/Q I/O” on the rear panel.

Run the I/Q Calibration

1. Turn the instrument on and let it warm up for 30 minutes.

2. Press:

I/Q > I/Q Calibration > Calibration Type Full > Execute Cal

Verify Instrument Calibration

The new baseband generator will function properly in most applications, without re-calibrating the signal

generator. If the application is critical, with respect to EVM, the following performance tests are

recommended. Refer to the PSG Signal Generators Service Guide:

1. Self Test

2. I/Q 20 Prelevel Gain Mixer Bias, and Digital Gain Cal

3. I/Q Impairment Calibration

4. EVM and IQ Offset

5. External Digital Modulation Level Accuracy Relative to CW

6. Dual Arbitrary Waveform Generator Check
