6.3 Performance Tests
6.3.3 Relative level accuracy of signal generator
Output level accuracy of output RF signal is measured during the open loop time
response.
(1) Specifications
• Relative level accuracy: ±0.2 dB/20 dB
(when the level is variable in the time response mea-
surement of open loop power control at 18 to 28 ˚C)
(2) Test instruments
• Power meter: ML4803A or the equivalent
• Power sensor: MA4602A or the equivalent
• 30-dB attenuator for sensitivity adjustment:
MP47A or the equivalent
• PC
