Test Considerations
To ensure proper instrument operation, verify that you have selected the
correct power line voltage prior to attempting any test procedure in this
chapter. See page 22 in chapter 2 for more information.
For optimum performance, all test procedures should comply with the
following recommendations:
Verify the function generator is set to the default power on state
(power on default). A procedure is given on page 41.
Make sure that the calibration ambient temperature is stable and
between 18
C and 28 C.
Make sure ambient relative humidity is less than 80%.
Allow a 1-hour warm-up period before verification or adjustment.
Use only RG-58 or equivalent 50W cable.
Keep cables as short as possible, consistent with the impedance
requirements.
