5.5 Entering Commands
Commands for the calibrator may be entered in upper or lower case. There is at least one
space required between the command and parameter, all other spaces are optional. Almost
all commands for the calibrator are sequential, any overlapped commands will be indicated
as such. This section will briefly explain each of the commands and describe their general
use, which will include any parameters that may be entered with the command as well as
what the output of the command is.
5.5-1 Common Commands
*CLS
Clears the ESR, the error queue and the RQS bit. Also terminates all pending operations.
When writing programs, use before each procedure to avoid buffer overflow.
*ESE
Loads a byte into the Event Status Enable register. The command is entered with a decimal
number that, when converted to binary, enables the right bits in the Event Status Register. For
example:
*ESE 133
When 133 is converted to binary it is 10000101. Bits 7, 2, and 0 will be enabled.
*ESE?
Returns the contents of the Event Status Enable register. The value returned is a decimal. For
example, if the register has the following settings:
10000101 than the value returned will be 133.
*ESR?
Returns the contents of the Event Status Register in decimal form. For example:
If the ESR contains 10111001, *ESR? will return 185.
*IDN?
Returns the manufacturer, model number, and firmware revision of the Calibrator. For
example:
*IDN? will return MARTEL, PSC4010, 250, 1.00
*OPC
Enables the Operation Complete setting in the ESR. This setting makes it possible to check if
an operations is complete after it has been initialized.
For example this operation could be used with the command TRIG.
