Test Considerations
For optimum performance, all procedures should comply with the following
recommendations:
Updating SDG‟s firmware to the newest version is strongly recommended.
Assure that the calibration ambient temperature is stable and between
18℃ and 28℃. Ideally, the calibration should be performed at 23℃±1℃.
Assure ambient relative humidity is less than 80%.
Allow a 30 minute warm-up period before verification or adjustment.
Keep the measurement cables as short as possible, consistent with the
impedance requirements.
Use a 50 Ω coaxial cable.
Performance Verification Test
The performance verification tests are recommended as acceptance tests
upon receipt of the instrument. The acceptance test results should be
compared against the specifications given in chapter 1. After acceptance,
repeat the performance verification tests at every calibration interval.
If the instrument fails performance verification, adjustment or repair is required.
