5 Launch the Interactive IO on the Keysight IO Libraries Suite.
6 Set the frequency of the DUT to 50 MHz by sending "FREQ 50MHz".
7 Enable auto-averaging for the DUT by sending "AVER:COUN:AUTO ON".
8 Change the power measurement unit of the DUT to watt by sending
"UNIT:POW W".
9 Set the DUT to the single trigger mode by sending "INIT:CONT OFF".
10 Perform zeroing for the DUT by sending "CAL:ZERO:AUTO ONCE" and wait for
the power meter to complete the zeroing process.
11 Read the noise level of the DUT by sending "READ?" and then record the
reading.
12 Repeat 10 times, step 11 to step 12 and then calculate the mean value of the
readings.
13 Compare the calculated mean value to the product datasheet. If the
