1594A/1595A Super-Thermometer

Interface Commands

The returned value is a resistance ratio after processing by the digital lter. If no measurement is available, no

response is returned and error code -230, “Data corrupt or stale” is generated in the error queue.

8.7.3.89 STAT:OPER?

Example response: 16

Reads and clears the Operation Status Event Register. This indicates whether a new measurement became

available to read (using FETC?) since the previous STAT:OPER? query. The return value is 16 if a new mea-

surement has been acquired and 0 otherwise. Reading the Operation Status Event Register using this command

clears the register. The register is also cleared when a *CLS or FETC? command is received.

8.7.3.90 STAT:OPER:COND?

Example response: 16

Reads the Operation Status Condition Register. This indicates whether or not measurement is enabled. The

return value is 16 if measurement is enabledand 0 otherwise. Reading the Operation Status Condition Register

does not change it.

8.7.3.91 STAT:OPER:ENAB <value>

Example command: STAT:OPER:ENAB 16

Query form: STAT:OPER:ENAB?

Alternate parameter: DEF

Sets the Operation Status Enable Register. This mask register determines which corresponding bits of the Op-

eration Status Event Register affect the Operation Status Bit (OSB, bit 7) of the Status Byte Register. A value

of 16 enables reporting when a new measurement is acquired. The default setting is 0.

8.7.3.92 STAT:QUES?

Example response: 16

Reads and clears the Questionable Status Event Register. This indicates whether a new measurement that was

erroneous or questionable was acquired since the previous STAT:QUES? query.

The bits in the Questionable Status Event Register correspond to the bits in the Questionable Status Condition

The difference is the bits in the Questionable Status Event Register remain set after the condition no longer ex-

ists. Reading the Questionable Status Event Register using the STAT:QUES? command clears the register. The

8.7.3.93 STAT:QUES:COND?

Example response: 16

Reads the Questionable Status Condition Register. This indicates whether the latest measurement was errone-

ous or questionable.

The return value is 16 if the latest measurement is questionable and 0 otherwise. The Questionable Status

Condition Register is cleared when a new valid measurement is acquired. Reading the Questionable Status

Condition Register does not change it.

8.7.3.94 STAT:QUES:ENAB <value>

Example command: STAT:QUES:ENAB 16

Query form: STAT:QUES:ENAB?

Alternate parameter: DEF

Sets the Questionable Status Enable Register. This mask register determines which corresponding bits of the

Questionable Status Event Register affect the Questionable Status Bit (QSB, bit 3) of the Status Byte Register.

A value of 16 enables reporting of questionable measurements. The default setting is 0.
