5.4.2. GENERAL SYNTAX FOR NUMBERS
Numeric parameters may have up to 30 characters, and although the 6530 will accept
numeric parameters in the range ±2.2E-308 through ±1.8E308, the useful range of
numbers is between ±1.0E-8 and ±1.0E5.
The portion of the command parser that interprets numeric input will correctly recognize
most common forms of numeric input, for example the following are all valid methods of
expressing the number 123.4:
•
123.4
•
123.4e00
•
0.1234E3
•
1234e-1
•
0000123.4
The following are examples of invalid forms of expressing a number:
•
123.4 e00 space between mantissa and exponent letter
•
1234D-1 exponent not e or E
•
n123.4 letter in front of the first digit
•
e34 missing mantissa
Multipliers (such as µ, m, k, and M) are not permitted on commands, all numbers must be
entered in the base units, for example 100 mV can be expressed as 100e-3 or 0.100.
Expressions (for example 7 + 20 X 3) are not allowed as parameters.
5.4.3. REMOTE AND LOCAL OPERATION
The 6530 can be operated using the front panel keys or it can be operated remotely using a
remote controller.:
5.4.4. LOCAL
The 6530 responds to local and remote commands. This is also called "Front Panel
Operation". Only remote commands that do not affect the state of the 6530 are allowed to
execute. (For example the command SENSe:CAPacitor? is allowed to operate but the
command SENSe:CAPacitor 27 which would change the instrument state is not allowed.)
If the controller sends a command which would affect the instrument state while in local,
the command will be ignored, and an Execution Error indication will be given.
5.4.5. REMOTE
When the Remote Enable (REN) line is asserted and the controller addresses the 6530 as
a listener, the 6530 enters the remote state.
