When BIT cards are installed, the computer interfaces (GPIB. LAN) use 16 bit Digital to Analog circuits to control the BOP units. When these interfaces are installed, refer to model-specific specifications of the combined BOP with BIT card.

| (1) | Output effects, expressaed as a percentage, re referred to the minimum rated output voltage or curent, |
| (2) | Measured with the common terminal grounded so that the common mode current does not flow through the load. |
| (3) | Peak-to-peak ripple is measured over a 20Hz to 10MHz bandwidth. |
| (4) |
The output effect can be calculated by the relationship: ΔEO = �ΔEr (Rf/Ri) �ΔEio (1+Rf/Ri) �ΔIio (Rf) where Rf is the feedback resistor and Ri is the input resistor from the reference Er. |
| (5) | For BOP 200-1M the maximum ripple and noise is 5mV rms and 50mV p-p. |
| (6) | For all BOP models (except BOP 200-1M) with BIT card installed: typical voltage mode ripple/noise = 4mV rms, max noise = 6mV rms and 60mV p-p, For BOP 200-1 models with BIT card installed: typical voltage mode ripple/noise = 4mV rms, max voltage mode ripple/noise = 8mV rms and 80mV p-p. |
| (6) | For BOP 5-20DL, typical voltage mode output effects = 0.004%, maximum voltage mode output effects = 0.008%. |
