INPUT and OUTPUT connectors

Figure 2-1
Each of these connectors has the following function:
• INPUT CHANNEL 1: A 3-lug triax connector for direct current input from the photo-
diode or other DUT to channel 1.
• INPUT CHANNEL 2: A 3-lug triax connector for direct current input from the photo-
diode or other DUT to channel 2.
• VOLTAGE SOURCE CHANNEL 1 OUTPUT: A safety banana jack used to apply the
channel 1 HI voltage bias source signal to the photodiode or other DUT.
• VOLTAGE SOURCE CHANNEL 2 OUTPUT: A safety banana jack used to apply the
channel 2 HI voltage bias source signal to the photodiode or other DUT.

Maximum common-mode voltage (voltage between INPUT analog
common and chassis ground) is 200V. Exceeding this value may result
in a shock hazard.
When making connections, do not leave any exposed connections. Be
sure that all external circuits are properly insulated.
Maximum INPUT and OUTPUT connector rating is 100V @ 20mA.
Exceeding these values may result in instrument damage.
