CONTrol:EXTernal:TESTset:DATa <addr>,<data>

(Read-Write) Reads and writes 13 bits of data to the specified address using the AD0 through AD12 lines of the external test set connector. The instrument generates the appropriate timing signals (strobes the address, then the data) to control an external test set.

Parameters

 

<addr>

Decimal equivalent of the 13 bit binary address.

<data>

Decimal equivalent of the 13 bit binary data

Examples

CONT:EXT:TEST:DATA 12,3
CONTrol:external:testset:data 12,3

Query Syntax

CONTrol:EXTernal:TESTset:DATA? <addr>

'Reads the decimal equivalent of the binary data from the specified address

Return Type

Numeric

Default

Not Applicable


CONTrol:EXTernal:TESTset:INTerrupt?

(Read-Only) Reads the boolean state of the Interrupt In line (pin 13) on the external test set connector.

Examples

CONT:EXT:TEST:INT?
control:external:testset:interrupt?

Return Type

Boolean

False (0) - the line is being held at a TTL High.

True (1) - the line is being held at a TTL Low.

Default

Not Applicable


CONTrol:EXTernal:TESTset:RAWData <data>

(Read-Write) Reads and writes 16 bits of data through the AD0 through AD12 and three timing lines of the external test set connector. Does NOT generate appropriate timing signals.

Use of this command requires detailed knowledge of all 16 bits. Refer to the Data format table.

Note: During a WRITE, Bit 13 must always be low. Otherwise Bit 0-12 will tristate

Parameters

<data>

Decimal equivalent of the binary data.

*These lines are dependent on the state of RLW (pin25).
Writing a 0(low) to RLW will set lines AD0-AD12 to write mode.
Writing a 1(high) to RLW will set lines AD0-AD12 to read mode.

Default

CONTrol:EXTernal:TESTset:SWEepholdoff?

(Read-Only) Reads the Sweep Holdoff Iine (pin 2) on the external test set connector.

Examples

CONT:EXT:TEST:SWE?
control:external:testset:sweepholdoff?

Return Type

Boolean

TRUE (1) - the pin is set to a TTL High

FALSE (0) - the pin is set to TTL Low

Default
