Trimming the Analog Output
(-AO Option)
Figure 4.9 gives an overview of the Analog Output Trimming menu.
Output trimming increases the measurement accuracy of the STA by calibrating its analog output
to the device that is receiving the output. This ensures that the instrument is being correctly
interpreted.
Connect the unit as shown in Figure 4.10 and allow five minutes for warm up and stabilization.
