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.  

Note 

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 

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.
