Performance Test and Operation Verification
This test verifies that the Agilent 89410A meets its amplitude accuracy
specification for absolute full-scale accuracy. In this test, the output of the
synthesizer is connected to a 1 dB and a 10 dB step attenuator. With the
attenuators set to 20 dB, the synthesizer’s amplitude is adjusted for a 0 dBm
reading on the milliwatt power meter. The output of the attenuators is then
connected to the Agilent 89410A, and the attenuators are set for the desired
output level. This test checks −30, −18, −6, +6, and +18 dBm at 9.876 MHz
and 49.234 kHz in the 50 ohm and 1 Mohm impedance paths. The following
lists the attenuator settings for each amplitude:
Amplitude −30 dBm −18 dBm −6 dBm +6 dBm +18 dBm
10 dB Step Attenuator 50 dB 30 dB 20 dB 10 dB 0 dB
1 dB Step Attenuator 0 dB 8 dB 6 dB 4 dB 2 dB
