5725A AMPLIFIER

The 5725A Amplifier enhances the 5700A Series Multifunction Calibrators in the ac voltage, ac current, and dc current functions. The 5725A operates under complete control of the 5700A Series calibrators through an interface cable supplied with the 5725A.

Enhancements to 5700A/5720A ac voltage output capability provided by the 5725A:

• Frequency limits at higher voltage increase to 100 kHz at 750 V, 30 kHz at 1100 V
• Load limits are to 70 mA for frequencies above 5 kHz, and to 50 mA for frequencies less than 5 kHz
• Capacitive load limits are increased to 1000 pF
