Option 001; Option 002 - HP 3580A Operating And Service Manual

Model 3580A GENERAL OPERATING INFORMATION
Section III
The instrument should not be left in the
CHARGE mode for prolonged periods. A
charge period of 14 hours is sufficient to
recharge a fully discharged battery pack. Ex-
tended periods of overcharge in ambient tem-
peratures exceeding 30° C ( 86° F) will severely
degrade battery life and capacity by causing the
cells to overheat.
3-186. Temperature Limits.
To prevent battery damage,
the following temperature limits must be observed:
a. Operating Temperature: 0° C ( + 3 2° F) to + 40° C
(+ 104°F)
b. Charge Temperature Range: 0°C (+ 32°F) to+ 40°C
(+ 104° F)
c. Storage Temperature Range: - 40° C (- 40° F) to
+ 50°C (+ 122°F)
3-187. Option 002.
3-188. The 3580A Option 002 is equipped with a front
panel slide switch which permits selection of three input
configurations: Unbalanced, Balanced Bridged, and Bal-
anced Terminated. These input configurations are illustra-
ted in Figure 3-32. In addition, the 3580A Option 002
TRACKING OSC OUT is transformer coupled to provide a
600-ohm balanced output configuration.
~I
The differential signal level applied to the
Option 002 Balanced Terminated input must
not exceed+ 27 dBm at 0 V de. The combined
ac and de levels must be such that the power
dissipated by the terminating resistor is less
than 0.5 watt.
3-189. The 3580A Option 002 can be calibrated for
absolute measurements in rms volts, dBm/600 ohms or

dBm/900 ohms. The selection is made using the front panel
dBm 900 ohm/LIN - - dBm 600 ohm slide switch. Relative
measurements can be made in dB or percent of full scale.
3-190 It should be noted that in the unbalanced input
configuration, the input shunt capacitance is 40 pF, nomi-
nal. This differs from the 30 pF shunt capacitance of the
standard Model 3580A. If a 10:1 divider probe is used, it
must have sufficient adjustment range to compensate for
the 40 pF shunt capacitance. An -hp- Model 10003A
Voltage Divider Probe is recommended.
