Getting Started Wideband AC Voltage Module (Option 5700A-03) 3 Wideband AC Voltage Module (Option 5700A-03) The Wideband AC Voltage Module (Option 5700A-03) can be installed in both the 5700A and 5720A Series II Calibrators. The module is a high-accuracy, low-noise, extremely flat ac voltage source for calibrating rf voltmeters, with a frequency range of 10 Hz to 30 MHz. Output is in seven ranges from 300 V (-57 dBm) to 3.5 V (+24 dBm) through a Type-N coaxial connector into a 50 load. The output level is selected in volts or dBm through either the front panel controls or under remote control. The wideband module also functions with the calibrators output adjust controls that let display the error of a wideband meter in either percentage of output or in decibels. Included with the wideband module is a Type-N output cable and a 50 terminator. The wideband module is calibrated to the end of its standard-equipment output cable. Auxiliary Amplifier The Fluke Model 5725A Amplifier is available to extend the high voltage performance and current range of the calibrator: Interface connectors on the calibrators rear panel accept cables to directly operate a 5725A. Three amplifiers can be connected to the calibrator at the same time, but only one output can be active at a time. Once you have connected the amplifiers and configured the calibrator in a setup menu, amplifier operation is controlled by the calibrator. Operating instructions for the 5725A are provided in Chapter 4 of the Operators Manual. The General Specifications include specifications for operating the calibrator with the 5725A. For other amplifier specifications, refer to their instruction manuals. Table summarizes the extended capabilities offered by the 5725A. Brief descriptions of the extended capabilities follow.

Stability specifications are included in the Absolute Uncertainty values in the primary specification tables. 2. Temperature coefficient is an adder to uncertainty specifications that does not apply unless operated more than 5 C from calibration temperature, or calibrated outside the range 19 C to 24 C. Two examples: Calibrate at 20 C: Temperature coefficient adder is not required unless operated below 15 C or above 25 C. Calibrate at 26 C: Add 2 C temperature coefficient adder. Additional temperature coefficient adder is not required unless operated below 21 C or above 31 C. 3. Refer to current derating factors
