The programming resolution for each channel should be:
−*100V: 0.001V where a typical voltage is 71.770V.
−*10V: 0.01V where a typical voltage is 5.75V.
−*5V/10V: 0.01 where a typical voltage is 5.00V.

−We require the following voltages on the boards: ~72V for biasing, 5.75V for VCC, +5V. Therefore, a power supply with 100V, 10V, and 5V channels, or 100V, and 2x 10V channels, is required.
+We require the following voltages on the boards:
+# +100V (range 80V - 100V) for biasing
+#*1V steps from 80V - 100V
+#*typical operation at 85V
+#*maximum current demand 500mA (50W power)
+#*maximum ripple P-P 50mV @ f < 1kHz
+#*maximum noise P-P 5mV @ 1kHz < f < 5MHz
+#*maximum HF noise P-P 20mV @ f > 5MHz
+#*long-term variation < ±50mV (0.05%)
+# +6V (range 5.5V - 6.0V) for preamplifier VCC;
+#*0.01V steps from 5.5V to 6.0V
+#*typical operation at 5.75V
+#*maximum current 8A (50W power)
+#*maximum ripple P-P 50mV @ f < 1kHz
+#*maximum noise P-P 5mV @ 1kHz < f < 5MHz
+#*maximum HF noise P-P 20mV @ f > 5MHz
+#*long-term variation < ±50 mV
+# +5V for cmos logic VCC
+#*fixed 4.95V - 5.05V, no adjustment required
