6 Configure the differential amplifier as follows.
• Enable the AC mode (positive and negative) to remove
the DC component
• Enable the differential mode
• Set the gain to ×10
• Set the attenuation to 1
• Set the low- pass filter to 20 MHz bandwidth limit to
filter out input signals that contain higher frequencies
• Enable the zero precision voltage generator
• Set input impedance to 50 Ω
7 Configure the RMS voltmeter as follows.
• Set high- pass filter to 10 Hz
• AC coupling
8 Divide the reading of the RMS voltmeter by 10, and then
multiply the result by 5 to get the RMS noise
measurement. The result should not exceed the RMS
limits of 1 mA
