4.3.9 Average noise level
The internal noise distributed evenly in proportion to the resolution bandwidth over
the entire measurement frequency band is called the “average noise level.”
(1) Test target ratings
• Average noise level:
Resolution bandwidth 1 kHz, video bandwidth 10 Hz
At Main connector, input attenuator 20 dB
≤
–90 dBm (10 MHz to 2.2 GHz)
≤
–85 dBm (>2.2 GHz)
At Aux connector, input attenuator 0 dB
≤
–110 dBm (10 MHz to 2.2 GHz)
≤
–105 dBm (>2.2 GHz)
(2) Test equipment
• No-reflection terminator: MP752A
