Steps Before Executing a Zero Calibration:

The following steps must be completed prior to executing a zero calibration. Errors result if these steps are not performed before CAL:ZERO:ALL?.

1 Set CAL:STATe ON to allow calibration to occur.

2Set the digitizer to the desired filter on the channel you want to calibrate with INPut[<channel>]:FILTer:FREQ <freq> and :FILTer:STATe ONOFF.

Optional Parameters: Optional parameters that are left blank are filled from left to right. Therefore, it is necessary to use the syntax DEFault to note that a particular parameter is to use the default value. For example, to specify a sample rate other than the default, you must declare DEFault for the <readings> parameter or the <rate> parameter value you intended will be used to fill in the <readings> parameter. The command for channel 1 would appear as: CAL:ZERO1 DEF,.002.

Number of Samples and Sample Rate: The number of samples and the sample rate would normally be set to DEFault values to provide averaging over an integral number of either 50 Hertz or 60 Hertz power line cycles. This allows the calibration to cancel out any noise that is periodic with the power supply. Specifying a value other than DEF for <samples> and/or <rate> will result in those values being used.
