Keysight M9601A Startup Guide, Edition 2
Installing Interlock Circuit
CAUTION
Do not connect the interlock terminals to anything other than the interlock
circuit. Applying current or voltage to the terminals may damage the M9601A.
Requirements
• Mechanical switch (Keysight N1254A-402 or equivalent), 2 ea
• Connector-terminal block 2.5 mm 6-terminal, 1 ea
• BNC to ferrule terminal cable (Keysight PX0101A-001 (1.5 m) / 002 (3.0 m) or
equivalent), 1 ea
• BNC connector (jack to soldering terminals), 1 ea
• Connection wire
Procedure
1. Mount two mechanical switches onto your shielding box, so that the switches
close when the access door is closed, and open when the access door is
opened. See
for the switch dimensions.
2. Mount a BNC connector onto your shielding box. Be sure that the outer shield
of the BNC connector is electrically isolated from the shielding box.
3. Use a wire and connect the two switches in series between the soldering
terminals of the BNC connector as shown in
.
4. Connect the connector-terminal block to the M9601A.
5. Connect the BNC to ferrule terminal cable to the interlock terminals of the
M9601A.
6. Connect the BNC to ferrule terminal cable to the BNC connector on the
shielding box.
You can also connect the mechanical switches directly to the connector-terminal
block by using connection wire and ferrule terminals.
