5. Operating Instructions
This section provides an overview of the basic operation of the Tektronix AFG1022. For detailed instructions on specific functions, refer to the comprehensive user manual provided on the included CD.
5.1 Powering On and Initial Screen
- Press the power button located on the front panel to turn on the instrument.
- The display will show the Tektronix logo and then transition to the main waveform generation interface.
5.2 Basic Waveform Generation
The AFG1022 can generate various standard waveforms and arbitrary waveforms.
- Selecting Waveform Type: Use the dedicated buttons below the display (Sine, Square, Ramp, Pulse, Arb, Noise) to select the desired waveform.
- Setting Frequency: Use the numeric keypad and the rotary knob to input the desired frequency. The display will update in real-time.
- Setting Amplitude and Offset: Adjust the amplitude (Vpp) and DC offset (V) using the corresponding soft keys and the rotary knob.
- Enabling Output: Press the On/Off button for Channel 1 (Out1) or Channel 2 (Out2) to enable the waveform output. The button will illuminate when the output is active.

5.3 Advanced Functions
- Modulation: Press the Mod button to access modulation settings (AM, FM, PM, FSK, PWM).
- Sweep: Configure frequency sweeps by pressing the Sweep soft key.
- Burst: Generate burst waveforms by pressing the Burst soft key.
- Arbitrary Waveforms: The AFG1022 supports user-defined arbitrary waveforms. Refer to the full manual for instructions on creating and loading custom waveforms.
6. Maintenance
Proper maintenance ensures the longevity and optimal performance of your Tektronix AFG1022.
6.1 Cleaning
- Always disconnect the power cord before cleaning the instrument.
- Use a soft, dry cloth to wipe the exterior surfaces. For stubborn dirt, a cloth lightly dampened with mild detergent and water may be used.
- Do not use abrasive cleaners, solvents, or strong chemicals, as these can damage the plastic parts and labels.
- Avoid spraying liquids directly onto the instrument.
6.2 Fuse Replacement
If the instrument does not power on, check the fuse located in the power inlet on the rear panel. Ensure the replacement fuse matches the specified type and rating (e.g., 250V, 2A). Refer to the full manual for detailed instructions on fuse replacement.
6.3 Calibration
For continued accuracy, periodic calibration by qualified service personnel is recommended. Refer to the calibration certificate for the recommended calibration interval.
7. Troubleshooting
This section provides solutions to common issues you might encounter with your AFG1022. If the problem persists, contact Tektronix customer support.
| Problem | Possible Cause | Solution |
|---|---|---|
| Instrument does not power on. | No power, faulty power cord, blown fuse. | Check power cord connection. Verify power outlet. Check and replace fuse if necessary. Ensure line selector is correct. |
| No waveform output. | Output channel not enabled, incorrect amplitude/offset settings, faulty cable, incorrect load impedance. | Press the On/Off button for the desired channel. Verify amplitude and offset settings. Check BNC cable connections. Ensure load impedance matches instrument setting. |
| Display is blank or frozen. | Software error, internal fault. | Power cycle the instrument (turn off, wait 10 seconds, turn on). If issue persists, contact support. |
| Incorrect waveform shape/frequency. | Incorrect settings, external interference. | Double-check all waveform parameters (frequency, amplitude, offset, modulation settings). Ensure proper shielding of cables. |
