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

Applicable Models: N522xB, N523xB, N524xB (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?

Applicable Models: N522xB, N523xB, N524xB (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>

Applicable Models: N522xB, N523xB, N524xB

(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.

Format of data WRITTEN with RAWData:

Pin	Bit	Signal name
22	0	AD0*
23	1	AD1*
11	2	AD2*
10	3	AD3*
9	4	AD4*
21	5	AD5*
20	6	AD6*
19	7	AD7*
6	8	AD8*
5	9	AD9*
4	10	AD10*
17	11	AD11*
3	12	AD12*
25	13	RLW
24	14	LDS
8	15	LAS

* This Output will float if RLW (bit-13) is set high

Examples	CONT:EXT:TEST:RAWD 8001 CONTrol:external:testset:rawdata 1234
Query Syntax	CONTrol:EXTernal:TESTset:RAWData?
Return Format	Format of data READ with RAWData?

Pin	Bit	Signal name
22	0	AD0*
23	1	AD1*
11	2	AD2*
10	3	AD3*
9	4	AD4*
21	5	AD5*
20	6	AD6*
19	7	AD7*
6	8	AD8*
5	9	AD9*
4	10	AD10*
17	11	AD11*
3	12	AD12*
2	13	Sweep Holdoff In
13	14	Interrupt In (inverted internally)
na	15	Always Zero, grounded internally

	*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	Not Applicable

CONTrol:EXTernal:TESTset:SWEepholdoff?

Applicable Models: N522xB, N523xB, N524xB (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	Not Applicable
