Agilent Technologies 75000 SERIES B, E1301B, E1300B SYSTem COMMunicate SERialn RECeive PARity Type

SYSTem :COMMunicate: SERial[n] [:RECeive] :PARity [:TYPE]

•The following table defines each value of type:

Value	Definition
EVEN	If … PARity:CHECK is ON, the received parity bit
	must maintain even parity. The transmitted parity
	bit will maintain even parity.
ODD	If … PARity:CHECK is ON, the received parity bit
	must maintain odd parity. The transmitted parity
	bit will maintain odd parity.
ZERO	If … PARity:CHECK is ON, the received parity bit
	must be a zero. The transmitted parity bit will be a
	zero.
ONE	If … PARity:CHECK is ON, the received parity bit
	must be a logic one. The transmitted parity bit will
	be a logic one.
NONE	A parity bit must not be received in the serial data
	frame. No parity bit will be transmitted.

•While this command operates independently of either the … BITS or … SBITs commands, there are two combinations which are disallowed because of their data frame bit width. The following table shows the possible combinations:

… BITS	… PARity:TYPE	… SBITs	Frame Bits
7	NONE	1	9 - disallowed
7	NONE	2	10
7	Yes	1	10
7	Yes	2	11
8	NONE	1	10
8	NONE	2	11
8	Yes	1	11
8	Yes	2	12 - disallowed

•Received parity will not be checked unless … PAR:CHEC ON is has been sent. Transmitted data will include the specified parity whether

…PAR:CHEC is ON or OFF.

•DIAG:BOOT:COLD will set … PARity to NONE .

•Related Commands: … PAR:CHEC 1 0 ON OFF,

…SER[n]:BITS 7 8, … SER[n]:SBITs 1 2

•*RST Condition: No change

Example Set parity check/generation to ODD.
SYST:COMM:SER0:PAR ODD	Set parity type
SYST:COMM:SER0:PAR:CHEC ON	Enable parity check/gen.
