Example: Digital Test
Repeat for Ports 1 through 3
3.
• Repeat step 2 for ports 1, 2, and 3.
• Use SOUR:DIG:DATAn #Bssssssss and MEAS:DIG:DATAn?
where n = port number and ssssssss = the binary string.
• For Port 1 Write, use Port 3 Read. For Port 2 Write, use Port 0
Read. For Port 3 Write, use Port 1 Read.
Check Port 0 CTL and Port 2 FLG handshake lines
4.
• Send *RST to the module.
• Send SOUR:DIG:CONT0 1 to the module.
• Send MEAS:DIG:FLAG2? to the module.
• Enter the response. The response should be 1.
• Enter a Pass or Fail in Table 2-1.
• Send SOUR:DIG:CONT0 0 to the module.
• Send MEAS:DIG:FLAG2? to the module.
• Enter the response. The response should be 0.
• Enter a Pass or Fail in Table 2-1.
Repeat for Ports 1, 2, and 3
5.
• Repeat step 4 for ports 1, 2, and 3.
•
Send SOUR:DIG:CONTn f to the module where n = port
number and f = is a binary toggle (0 and 1).
• Send MEAS:DIG:FLAGn to the module where n = port
number.
• For Port 1 CTL, use Port 3 FLG. For Port 2 CTL, use Port 0
FLG. For Port 3 CTL, use Port 1 FLG.
Reset the module jumpers
6.
• Turn mainframe power OFF.
• Remove the Test Cable from the module.
• Remove the module from the mainframe.
• Reset the module jumpers to the positions recorded in Step 1.
This example performs a bit walk test of all bits on all ports and checks the
module's ability to set and reset the handshake lines on each port.
