Db Range Flatness Verification - Keysight 33210A Service Manual

+20 dB Range Flatness Verification

This procedure checks the high frequency ac amplitude flatness above
100 kHz on the +20dB attenuator range. (Flatness is relative to 1 kHz.)
1 Connect the power meter to measure the output voltage of the
instrument as shown below.
Caution
Most power meters will require an attenuator or special power head to
measure the +20 dB output.
2 Set up the function generator as follows:
• Output impedance: 50 Ω (press
• Waveform: Sine
• Frequency: 100 kHz
• Amplitude: 23.90 dBm
3 On the power meter, use the Relative Power function to set the current
reading as the reference value. This will allow you to compare future
measurement results in dB.
Make sure the output is enabled.
