Noise Equivalent Power
1. Power the P670XB under test using an 1103 Tekprobe power supply.
2. Connect the P670XB output channel from the 1103 power supply to the
power meter input with the 1 GHz filter in series with this connection.
3. With the dust cover on the input to the P670XB, the power meter reading
should be ≤ 15 nW for the P6701B and ≤ 7 nW for the P6703B.
