Front panel calibration
1. Connect the low-thermal short to the rear panel input jacks, and select the rear inputs
with the INPUTS switch. Allow three minutes for thermal equilibrium.
2. Press in and hold the OPEN key while turning on the power.
3. Press SHIFT then CAL, select RUN, then enter the appropriate calibration code (default:
002000).
4. Select ALL at the CAL:RUN prompt.
5. Press ENTER.
6. Perform the entire front panel comprehensive calibration procedure discussed earlier in
this section.
7. Connect the synthesizer to the Model 2000 INPUT jacks as shown in Figure 2-5. Select
the front input jacks with the INPUTS switch.
8. After the last AC current calibration step, the instrument will prompt you to enter 3Hz at
1V RMS and 1kHz. For each prompt:
• Low frequency cal: Set the synthesizer to output a 1V RMS, 3Hz sine wave. Use the
left and right arrow keys, and the range keys to adjust the displayed voltage value to
the value you measured and recorded earlier. Press Enter.
• Frequency cal: Set the synthesizer to output a 1V RMS sine wave at 1kHz. Enter
1.000000kHz, then press ENTER.
9. Set the calibration dates, then save calibration constants to complete the process.
