Section 19: Remote Commands

smuX.measure.autozero

X = SMU channel (a or b)

Attribute

Behavior of the SMU’s A/D internal reference measurements (autozero).

Default

smuX.AUTOZERO_AUTO

TSP-Link 
accessibility

This attribute can be accessed from a remote TSP-Link node.

Usage

azmode = smuX.measure.autozero 

-- Reads autozero.

smuX.measure.autozero = azmode 

-- Writes autozero.

azmode

Indicates status of autozero.

Set 

azmode

 to be one of the following values:

0

 or 

smuX.AUTOZERO_OFF

Autozero disabled.

1

 or 

smuX.AUTOZERO_ONCE

 

Performs autozero once, then disables autozero.

2

 or 

smuX.AUTOZERO_AUTO

 

Automatic checking of reference and zero measurements.

 

 

An autozero is performed when needed.

Remarks

• The Series 2600A uses a ratio metric A/D conversion technique. To ensure accuracy of 

readings, the instrument must periodically obtain fresh measurements of its internal ground and 
voltage reference. The time interval between needing to update these reference measurements 
is determined by the integration aperture being used for measurements. Separate reference and 
zero measurements are used for each aperture.

• By default, the instrument automatically checks these reference measurements whenever a 

signal measurement is made. If the reference measurements have expired when a signal 
measurement is made, the instrument will automatically take two more A/D conversions, one for 
the reference and one for the zero, before returning the result. Thus, occasionally, a 
measurement takes longer than normal.

• This extra time can cause problems in sweeps and other test sequences in which measurement 

timing is critical. To avoid the extra time for the reference measurements in these situations, the 

smuX.measure.autozero

 attribute can be used to disable the automatic reference 

measurements. Keep in mind that with automatic reference measurements disabled, the 
instrument may gradually drift out of specification.

• To minimize the drift, a reference and zero measurement should be made just prior to the critical 

test sequence. The

 smuX.AUTOZERO_ONCE

 setting can be used to force a refresh of the 

reference and zero measurements used for the current aperture setting. 

• Autozero reference measurements for the last 10 used NPLC settings are stored in a reference 

cache. If an NPLC setting is selected and an entry for it is not in the cache, the oldest (least 
recently used) entry will be discarded to make room for the new entry.

Example

Perform autozero once for SMU A:

smua.measure.autozero = smua.AUTOZERO_ONCE
