4-192 Agilent B1500A/B1505A Programming Guide, Edition 11
Command Reference
TDI
This command is not effective for the 4 byte binary data output format (FMT3 and
FMT4).
Syntax TDCV chnum,voltage
Parameters chnum : MFCMU source channel number. Integer expression. 1 to 10 or 101 to
1001. See Table 4-1 on page 4-16.
voltage : DC voltage (in V). Numeric expression.
0 (initial setting) to ± 100 V.
Source module is automatically selected by the setting value. The
MFCMU is selected if voltage is ± 25 V or less (setting resolution:
0.001 V), or the SMU is selected if voltage is greater than ± 25 V
(setting resolution: 0.005 V).
The SMU will operate with the 100 V limited auto ranging and 20 mA
compliance settings.
If the output voltage is greater than the allowable voltage for the
interlock open condition, the interlock circuit must be shorted.
Remarks To read the time data with the best resolution (100 μs), the timer must be cleared
every 100 sec or less for the FMT1, 2, or 5 data output format, or
every 1000 sec or less for the FMT 11, 12, 15, 21, 22, or 25 data output format.
Example
Statements
OUTPUT @B1500;"TDCV 7,1"
ENTER @B1500 USING "#,3X,13D,X";Time
TDI
Forces current and returns the time data from timer reset to the start of output. This
command is not effective for the 4 byte binary data output format (FMT3 and
FMT4).
Execution
Conditions
The CN/CNX command has been executed for the specified channel.
If the compliance value is greater than the allowable voltage for the interlock open
condition, the interlock circuit must be shorted.
Syntax TDI chnum,irange,current[,Vcomp[,polarity[,vrange]]]
