Output (HP): This high pass BNC output is the control signal from the proportional-
integral (P-I) filter and going to the DT1 filter section.
Power switch: This switch is pushed up to | position to turn on AC mains power to
LB2001.
AC Line Power Voltage Selector
Power entry module: The AC power cord must be connected between this instrument
receptacle and a properly grounded mains receptacle. The LB2001 can be configured
to operate with the following AC mains voltages: 100, 120, 220, and 230-240 VAC.
Please carefully read the preceding section Electrical Fuse & Voltage Selection for
instructions on installing the proper fuses and setting the correct AC supply voltage.
PI Filter Output Voltage Limit: This trim-pots determines the integrator voltage rails.
Sweep In 2: Input signals to this BNC connectors are summed into the Output signal.
Sweep In 1: This BNC input allows a low frequency periodic sweep signal to be
added to the output of the LB2001. The input impedance is 1k and the input voltage
range is -10V.. +10V. See Sweep Center and Sweep Span controls discussed below
for more details.
Int. Hold Input: This TTL logic input switches off the error signal input to the P-I
filter and holds the integrator output voltage at its current value
Error Monitor: This BNC output connector is a voltage monitor for the error signal
generated by the input difference amplifier. The DC-coupled error monitor has unity
gain with a nominal output voltage –10V..+10V.
