CAUTION

ABORTING AN ADJUSTMENT IN PROGRESS. Sometimes it

 

becomes necessary to abort an adjustment once the procedure has

 

been initiated. Issuing a remote interface device clear command will

 

abort the adjustment in progress.

 

Never turn off mainframe power while the digitizer is making an

 

adjustment. If power is removed during a zero adjustment, ALL

 

calibration memory may be lost. If power is removed during any gain

 

adjustment, calibration memory for the function being adjusted may

 

be lost.

 

 

 

 

NOTE The Agilent Technologies Universal Instrument Drivers CD received with

 

the E1563A or E1564A contains calibration and performance verification

 

program source code written in ANSI C. Calibration programs are

 

E1563CAL.C and E1564CAL.C. Performance verification programs are

 

E1563VER.C and E1564VER.C.

Zero Adjustment

 

 

 

This procedure sets the zero calibration constants for each digitizer range.

 

The digitizer calculates a new offset correction constant for the current

 

range when the CALibration:ZERO[<channel>] command is executed.

 

The zero adjustment procedure takes about 20 seconds per channel to

 

calculate new zero offset cal constants for all ranges of the channel.

 

The digitizer calculates a new set of offset correction constants for all ranges

 

of a channel when the CALibration:ZERO[<channel>]:ALL? command is

 

executed. The digitizer will sequence through all ranges automatically and

 

calculate new zero offset calibration constants automatically.

 

 

CAUTION

DO NOT REMOVE POWER. Do not remove power from the

 

mainframe during the digitizer's Zero Adjustment. You may lose

 

ALL calibration memory if power is removed while the digitizer is

 

adjusting.

 

 

1 Reset the Digitizer by executing *RST.

2Switch the internal short across each channel’s input by executing DIAG:SHORt<channel> for all channels. For example, DIAG:SHOR1; DIAG:SHOR2; etc.

3 Send CAL:VAL 0 <input> CALibration <value>.

4Perform the adjustment by sending CAL:ZERO<channel>:ALL? once for each channel and reading the calibration success result (a non-zero response indicates a calibration error occurred).
