5725A Amplifier
The Fluke 5725A Amplifier is an external unit that operates under Calibrator control to
extend ac voltage drive capabilities and both ac and dc current output range. The
amplifier adds the following capabilities to the Calibrator 1100 V ac range with no
compromise in accuracy:
• Frequency limits at higher voltage increase to 100 kHz at 750 V, 30 kHz at 1100V.
• Load limit increases to 70 mA for frequencies above 5 kHz.
• Capacitive drive increases to 1000 pF, subject to the maximum output current.
A separate set of binding posts on the front panel of the 5725A supplies extended-range
ac and dc current outputs. Since most meters have a separate input terminal for the high
current ranges, this eliminates the need to change cables during a procedure. A Calibrator
paired with a 5725A can also be configured to source all current (both standard
Calibrator-generated outputs and its own outputs) through the 5725A binding posts.
An interface connector on the Calibrator rear panel accepts the cable to directly operate a
5725A. Once the amplifier has been connected and the 5725A has been configured in a
setup menu, operation is controlled by the Calibrator.
Chapter 4 provides instructions for operating the 5725A amplifier. The general
specifications at the end of Chapter 1 include specifications for operating the 5730A
Calibrator with the 5725A. For other amplifier specifications, refer to their instruction
manuals. Table 1-1 summarizes the extended capabilities offered by each amplifier. Brief
descriptions of the extended capabilities follow.
52120A Amplifier
The 52120A is available to extend the current range of the Calibrator.
An interface connector on the Calibrator rear panel accepts the cable to directly operate
one or more 52120As in slave mode.
See Chapter 4 for operation instructions for the 52120A Transconductance Amplifier.
The general specifications at the end of Chapter 1 include specifications for operating the
Calibrator with one or more 52120As.
