3.8.4.1
VOLTAGE MODE
With the power supply in voltage mode (see Figure 3-15) and the digitally programmed output
voltage at zero, varying the high impedance voltage source from 0 to –1V causes the output
voltage of the power supply to vary linearly from 0 to E
O
max with a slope of (E
O
max) volts per
volt. The following equations give the output voltage as determined by a high impedance volt-
age source V
EXT
.
ANALOG PROGRAMMING, DIGITAL PROGRAMMING = 0:
Eo = (V
EXT
) x (11.1K/1.1K) x (–1) (10K/10K) x (–1) (R/10K)
= –(R) x |V
EXT
| (V d-c)
where
R =
Internal feedback resistance (K-ohms), determined by Model (see Table 3-10).
V
EXT
= External low impedance voltage source (Volts). This source can be either a d-c source
delivering a negative output voltage, or a function generator with an internal negative
bias. If the bias is not available from the function generator, use the digital programming
feature of the BHK-MG to provide proper bias to avoid clipping the waveform at the out-
put of the power supply.
ANALOG PROGRAMMING COMBINED WITH DIGITAL PROGRAMMING:
Eo = –(R x |V
EXT
|) – Eout
DP
(V d-c)
where
Eout
DP
= Output voltage programmed digitally (from either local keypad or remote GPIB bus)
(See above for definitions of R and V
EXT
.)
3.8.4.2
CURRENT MODE
With the power supply in current mode (see Figure 3-16) and the digitally programmed output
voltage at zero, varying the high impedance voltage source from 0 to –1V causes the output cur-
rent of the power supply to vary linearly from 0 to I
O
max with a slope of (I
O
max) mA per volt.
The following equations give the output current as determined by the low impedance voltage
source V
EXT
.
ANALOG PROGRAMMING, DIGITAL PROGRAMMING = 0:
Io =
[
(V
EXT
) x (11.1K/1.1K) x (–1 ) (10K/10K) x (–1/10) (10K/10K) ]/Rs
=
–(1/Rs) x |V
EXT
| (mA d-c)
where
Rs =Internal shunt resistance (kOhms), determined by Model (see Table 3-10).
(See above for definition of V
EXT
.)
ANALOG PROGRAMMING COMBINED WITH DIGITAL PROGRAMMING:
Io =
–(1/Rs) x |V
EXT

(mA d-c)
