NOTES: 1. The current control specification (stability) of BOP power supplies is not altered or improved by the addition of a BIT 4886
card. The current stability of the BIT 4886 card with most BOPs will be 0.015%. However, Some BOP models have better
control specifications, e.g., the BOP 20-5 (0.006% stability), and others have lower stability such as the BOP 100-4
(0.02%), BOP 50-4 (0.05%) and BOP 20-20 (0.1%). All stability measurements are after warm-up time of 5 minutes.
2. For all BOP models (except 200-1) with BIT 4886 card installed typical voltage mode ripple/noise = 4mV rms, max noise =
6mV rms and 60mV p-p. For BOP 200-1 models typical voltage mode ripple/noise = 4mV rms, maximum voltage mode rip-
ple/noise = 8mV rms and 80mV p-p.
3. Accuracy is affected by GPIB and RS-232 communications. To attain these accuracies only the Serial poll command of the
GPIB interface should be used while executing a transient or list.
