A
l00 Vac Input Power Option 100
General Information
Description
Option 100 is a modification of Agilent 6033A/6038A power supplies that involves changing a resistor in the A2 OVP
circuit, recalibrating the supply, and changing the Front Panel. These changes allow the units to operate at a lower line
voltage of 87 to 106 Vac, while operating on the same line frequency of 48 to 63 Hz. The reduced input voltage limits the
output power to 150W and the output voltage from 0 to 17V for the Agilent 6033A, and from 0 to 50V for the Agilent
6038A, while retaining the standard's unit output current rating. Other specifications that change due to Option 100 include
Programming Response Time, Overvoltage Protection and Remote Analog Programming.
Scope of Appendix A
This appendix contains all the information necessary to support Agilent 6033A/6038A power supplies that are equipped
with Option 100. The appendix describes only the changes pertaining to Option 100 and how they affect the other portions
of this manual. Unless otherwise specified in Appendix A, all other portions of the manual apply to both the standard unit
and the Option 100 unit.
Suggestions for Using Appendix A
The Option 100 changes are listed sequentially, starting with Chapter 1 in the main body of the manual and working back
through Chapter 6. It is recommended that the user mark all the necessary changes directly into his manual. This will update
the manual for Option 100 and eliminate the need for constant referrals back to Appendix A.
Chapter 1 Manual Changes
On Page 9, in Scope change the output power from 200 to 150 watts.
Chapter 2 Manual Changes
On Page 16, in Constant Voltage Full Scale Calibration, step b, change VSET 20 to VSET (6033A).
On Page 17, in Constant Voltage Full Scale Calibration, step d,
change 20.0025V to 17.0025V ± 600 µ V (6033A).
change 60.0075 to 50.0175V ± 1.52mV (6038A).
On Page 17, in Voltage Monitor and Remote Readback Full Scale Calibration step b, change VSET 60 to VSET 50
(6038A).
