INSTRUMENT AND MANUAL
IDENTIFICATION
1-17 Hewlett-Packard power supplies are identified by
a two part serial number. The first part is the serial number
prefix, a number-letter combination that denotes the date
of a significant design change and the country of manufac-
ture. The first two digits indicate the year (10 = 1970,
11= 1971, etc.) the second two digits indicate the week,
and the letter "A" designates the U.S.A. as the country of
manufacture. The second part is the power supply serial
number. A different sequential number is assigned to each
power supply, starting with 00101.
LOAD EFFECT TRANSIENT RECOVERY TIME:
All Outputs: Less than 50µsec for output recovery to
within 15mV of nominal output voltage following a load
change from full load to half load (or vice versa).
OUTPUT VOLTAGEOVERSHOOT:
All Outputs: During turn-on or turn-off of ac power,
output plus overshoot will not exceed 1 V if the output
control is set for less than 1V. If the control is set for 1V
or higher, there is no overshoot.
TEMPERATURE COEFFICIENT:
All Outputs: Less than 0.02% plus 1 mV voltage
change per degree Celsius over the operating range from
0 to 40°C after 30 minutes warm-up.
*OUTPUT IMPEDANCE (typical):
0 to +20V Output: 0.5m
0 to -20V Output: 0.5m
Model 6236B
0 to +6V Output: 0.3m
Model 6237B
0 to +18V Output: 0.3
* Operating characteristics listed as typical are provided
for the user's information only and are not warranteed

ORDERING ADDITIONAL MANUALS

1-20 One manual is shipped with each power supply
unless Option 910 is ordered for each extra manual. Addi-
tional manuals may be purchased from your local Hewlett-
Packard field office (see the list at the rear of this manual
for addresses). Specify the model number, serial number
prefix, and the HP Part Number provided on the title page.

panel voltage control)
0 to ±20V Outputs: 70mV
Model 6236B
0 to +6V Output: 20mV
