Calibration
Required Modules for Different Input/Output Signal Combinations
Consider the type of your instrument before doing a calibration:
• What are the input and output quantities/ports?
• Is the input signal measured, generated/simulated, controlled
or keyed (Input method)?
• Is the output signal measured or keyed (Output method)?
Use the following tables find out the required modules for each sup-
ported input/output quantity and method:
