Specifying a channel
The channels on the cards that you can use with the Model 707B or 708B are referred to by a
channel specifier. You will use the specifier to identify channels for use with close and open
operations, scans, and channel patterns. The specifier is used for all interfaces (front panel, web, and
remote command).
A channel specifier is a four or five-digit alphanumeric sequence. The first digit is always the slot
number of the slot in which the card is installed in the instrument. The remaining digits vary
depending on the type of card.
The following sections describe the channel specifier in more detail and provide generic examples
(which may or may not be suitable for your installed cards).
Channel types
The Models 707B and 708B support cards with matrix channels. The documentation for your card
model lists the available channel types.
Specify multiple channel numbers using lists. Lists build on the individual channel specifier.
Matrix card channel specifiers
The channels on the matrix cards are referred to by their slot, bank, row, and column numbers:
•
Slot number
: The number of the slot in which the card is installed.
•
Bank number
: The bank number, if used by your card. See your card documentation.
•
Row number
: The row number is either 1 to 8 or A to Z. See your card documentation.
•
Column number
: Always two digits. For columns greater than 99, use A, B, C and so on to
represent 10, 11, 12, …; the resulting sequence is: 98, 99, A0, A1, …, A8, A9, B0, B1, …
