Calibrate the Wideband AC Module (Option 5700A-03)

The Wideband AC Module (Option 5700A-03) can be installed in the Product.
The module needs to be calibrated for both gain and flatness. The gain should be
calibrated when the 5730A main output functions undergo their routine
calibration.
Since frequency flatness is determined by stable parameters (for example, circuit
geometry and dielectric constants), the flatness of the Wideband AC Module has
excellent long-term stability. Consequently, a two-year calibration cycle is
adequate for flatness calibration and can be scheduled to coincide with the
Product shipment to a standards laboratory for periodic verification.
The subsequent procedure describes the process for wideband gain calibration.
To do this procedure, a Type "N" female to double banana plug
adapter is necessary. This adapter comes with the Product.
Before this procedure is started, make sure the Product is powered on and has
completed an appropriate warm-up period. To calibrate the wideband gain:
1. Touch Setup Menu>Calibration to show the Calibration menu.
2. Connect the wideband output cable between the WIDEBAND connector and
40
the SENSE binding post.
The center conductor of the 50 Ω feedthrough should go to SENSE HI as
shown in Figure 4. The GND tab on the adapter should be on the LO side.
