Test Considerations

Verify that you have selected the correct power line voltage prior to attempting any test procedure to ensure proper instrument operation.

For optimum performance, all test procedures should comply with the following recommendations:

•Verify the function generator is set to its reset state (*RST).

•Assure that the calibration ambient temperature is stable and between 18° C and 28° C.

•Assure ambient relative humidity is less than 80%.

•Allow a 30 minute warm-up period before verification or adjustment.

•Use only RG-58 or equivalent 50 Ω cable.

•Keep cables as short as possible, consistent with the impedance requirements.
