Channel Numbering
The slot and channel addressing scheme used in the programming examples
follow the general form sxxx where s is the slot number for the 34980A mainframe
(1 through 8) and xxx is the three-digit channel number. Channel numbers for the
matrix modules are derived as shown in the following table:
The 34980A Web Browser interface, offers the easiest method to view the channel
map for any set configuration of the module.
For complete guidance on LAN connection and navigating the 34980A Web
Browser Interface, see the “Getting Started” chapter of the 34980A Mainframe
Users Guide.
34934A Module Channel Numbering
Each row, column intersection has a unique channel number.
This 4-digit channel number is of the form sxxx,
where s is the mainframe slot# for the 34934A module.
Calculate xxx from row R and column C, as shown below
4x32
(4 matrices)
for M1H: xxx = 100(2R-1) + C
for M2H: xxx = 100(2R-1) + C +32
for M1L: xxx = 100(2R-1) + C +64
for M2L: xxx = 100(2R-1) + C +96
4x64
(2 matrices)
for MH: xxx = 100(2R-1) + C
for ML: xxx = 100(2R-1) + C +64
4x128
xxx = 100(2R-1) + C
8x32
(2 matrices)
for MH: xxx = 100R + C
for ML: xxx = 100R + C +32
8x64 xxx = 100R + C
16x32 xxx = 50(R+1) + C
Examples:
in slot #1, 8x64 matrix, you need to address row 3, column 16
Then xxx = 100(3) + 16
= 316, so the channel # is 1316
----------------------------------------------------------------------------------------
in slot #2, 4x32 matrix M2H, you need to address row 4, column 21
Then xxx = 100(2x4 -1) + 21 +32 = 753, so the channel # is 2753
