Remote Operations 13-11
Parameter types
— The following are some of the more common parameter types:
<b> Boolean
— Used to enable or disable an instrument operation. 0 or OFF dis-
ables the operation, and 1 or ON enables the operation. Example:
:CALCulate1:STATe ON
Enable Calc 1 math expression
<name> Name parameter — Select a parameter name from a listed group.
Example:
<name> = NEVer
= NEXt
:TRACe:FEED:CONTrol NEXt
<NRf> Numeric representation format
— This parameter is a number that can be
expressed as an integer (e.g., 8), a real number (e.g., 23.6), or an exponent
(2.3E6). Example:
:SYSTem:KEY 11
Press EXIT key from over the bus
<n> Numeric value
— A numeric value parameter can consist of an NRf number
or one of the following name parameters: DEFault, MINimum, MAXimum.
When the DEFault parameter is used, the instrument is programmed to the
*RST default value. When the MINimum parameter is used, the instrument
is programmed to the lowest allowable value. When the MAXimum param-
eter is used, the instrument is programmed to the largest allowable value. Ex-
amples:
:ARM:TIMer 0.1
Sets timer to 100 msec.
:ARM:TIMer DEFault Sets timer to 0.1 sec.
:ARM:TIMer MINimum Sets timer to 1 msec.
:ARM:TIMer MAXimum Sets timer to 99999.99 sec.
<numlist> Numlist
— Specify one or more numbers for a list. Example:
:STATus:QUEue:ENABle (-110:-222) Enable errors -110
through -222
<NDN> Non-decimal numeric
— This parameter is used to send values in the bina-
ry, octal, or hexadecimal format. The prefix designates the format type:
#Bxx...x
#B specifies the binary format.
xx...x is the binary number (using 0s and 1s).
#Qxx...x #Q specifies the octal format.
xx...x is the octal number (values 0 through 7).
#Hxx...x #H specifies the hexadecimal format.
xx...x is the hexadecimal number (values 0 through
9 and A through F).
Examples to send the decimal value 36 in the non-decimal formats:
*ESE #b100100
Binary format
*ESE #q44 Octal format
*ESE #h24 Hexadecimal format
