• Repeat step 3 for channels 01 through 15

• Use CLOS (@nncc), where nn is the card number and cc is the

channel number

LO Channel

Measurements 1. Make Hardware Connections

• Turn mainframe power OFF

• Connect DMM as shown in Figure 2-3

• Turn mainframe power ON

2. Check for Stuck Channels

• Send *RST to the FET Multiplexer to open all channels

• Trigger the DMM with TRIG SGL and note reading

• Verify the reading is greater than 10 kΩ

3. Check LO Closed Channel Resistance

• Send CLOS (@nn00) to close channel 00, where nn is the card

number (typically 01)

• Trigger the DMM with TRIG SGL and note the reading

• Enter the result in Table 2-1 for channel 00 LO

• Send OPEN (@nn00) to open channel 00, where nn is the card

number

4. Repeat for Channels 01 through 15

• Repeat step 3 for channels 01 through 15

• Use CLOS (@nncc) and OPEN (@nncc), where nn is the card

number and cc is the channel number
