ISCE1?
Sequential Overlapped
Coupled
IEEE-488 RS-232
x x xx
x
(Instrument Status 1 to 0 Change Enable query) Return the two bytes from the 16-bit
ISCE1 register. (See “Instrument Status Change Enable Registers” in Chapter 5 for more
information.)
Response: <value> (decimal equivalent of the 16 bits, 0 to 32767)
Example: ISCE1? returns 4108
Return decimal 4108 (binary 0001000000001100) if bits 12 (SETTLED), 3
(IBOOST), and 2 (VBOOST) are set to 1.
ISCR?
Sequential Overlapped
Coupled
IEEE-488 RS-232
x x xx
x
(Instrument Status Change Register query) Returns and clears the contents of the
Instrument Status 0 to 1 Change Register (ISCR0) and Instrument Status 1 to 0 Change
Register (ISCR1). (See “Instrument Status Change Register” in Chapter 5 for more
information.)
Response: <value> (decimal equivalent of the 16 bits, 0 to 32767)
Example: ISCR? returns 4108
Return decimal 4108 (binary 0001000000001100) if bits 12 (SETTLED) and 3
(IBOOST) are enabled (set to 1) in the Instrument Status 0 to 1 Change Register and bits
12 (SETTLED) and 2 (VBOOST) are enabled (set to 1) in the Instrument Status 1 to 0
Change Register.
ISCR0?
Sequential Overlapped
Coupled
IEEE-488 RS-232
x x xx
x
(Instrument Status 0 to 1 Change Register query) Returns and clears the contents of the
Instrument Status 0 to 1 Change Register.
Response: <value> (decimal equivalent of the 16 bits, 0 to 32767)
Example: ISCRO? returns 4108
Return decimal 4108 (binary 0001000000001100) if bits 12 (SETTLED), 3
(IBOOST), and 2 (VBOOST) are set to 1.
ISCR1?
Sequential Overlapped
Coupled
IEEE-488 RS-232
x x xx
x
(Instrument Status 1 to 0 Change Register query) Returns and clears the contents of the
Instrument Status 1 to 0 Change Register.
Response: <value> (decimal equivalent of the 16 bits, 0 to 32767)
Example: ISCR1? returns 4108
Return decimal 4108 (binary 0001000000001100) if bits 12 (SETTLED), 3
(IBOOST), and 2 (VBOOST) are set to 1.
