Overview 

The PGA 1241 is a linear, extremely broadband precision power amplifier for the frequency range from DC to 300 kHz, predestined for all applications requiring fast-changing signals with high power. The power stage with 250 W (800 W) delivers a maximum output current up to 5 A (16 A) with a voltage gain of 10.

The integrated function generator supplies sine, triangle, or square wave signals, which are amplified by the built-in power amplifier. External signals can be added via an additional input.

All functions of this generator/amplifier combination can be controlled via the application software supplied, which allows complete remote control of the PGA 1241 via the USB interface. The integration into already existing automated test systems is made possible by the disclosure of the interface commands.

Key facts

  • Linear circuit design guarantees the lowest distortion, no interference, and high stability
  • Remote control via a USB interface for automatic test equipment
  • Ideal for operation on low impedance loads (e.g. Helmholtz coils)
  • Two different operating voltages optimize the power dissipation for loads with low impedance IEC

 

Applications            

Tests according to IEC / EN 61000-4-16

At 61000-4-16 the PGA 1241 is designed for the continuous disturbance variables (test level 1 to 4 and X to 50V), for the short time disturbance variables up to 300 V the PGA 1331 is required. Both devices can be operated as stand-alone units and integrated into existing test systems. If both continuous disturbance variables and short-term disturbance variables are to be tested, PGA 1241 and PGA 1331 are required and connected together.

 

Tests according to IEC / EN 61000-4-19

The PGA 1241 can be used as a test generator for both differential voltage and differential current testing according to IEC / EN 61000-4-19 incl. Appendix C (electricity meter). Since a constant current is required as a disturbing signal and the PGA 1241 generates voltage signals, an external multimeter (which supports SCPI) and an adapter are required for tests according to Appendix C.

The multimeter measures the voltage across the adapter, the program calculates the current currently flowing and controls the output of the PGA 1241. 

Tests according to IEC / EN 61543

The tests according to IEC/EN 61543 are carried out in the frequency band from 1 kHz to 150 kHz and require a constant current as an interference signal. The PGA 1241 generates a voltage signal and therefore requires an additional multimeter and adapter to meet the requirements of the IEC/EN 61543 standard. The multimeter measures the voltage and the program of the PGA 1241 calculates the current and readjusts the voltage.

 

General applications

The generation and amplification of small signals to produce larger output signals is a necessary practice in all areas of electrical engineering. The PGA 1240 is the ideal instrument for this. Due to the excellent signal quality and the remote control via USB interface, the PGA 1241 is the ideal choice for automatic test equipment.

 

Low resistance loads

The PGA 1241 is ideally suited for operation with low impedance loads (e.g. Helmholtz coils). The possible halving of the operating voltage reduces the power loss accordingly.

Waveform

The generator of the PGA 1241 provides 3 different waveforms: sine, triangle, and square. The frequency resolution is 0.05 Hz from DC to 300 kHz. With all waveforms, it is possible to superimpose a common-mode voltage.

Technology

A completely linear circuit design guarantees the lowest distortion, noise-free operation, and high stability. Two different operating voltages optimize power dissipation with low impedance loads.

Safety devices

The tests according to IEC/EN 61543 are carried out in the frequency band from 1 kHz to 150 kHz and require a constant current as an interference signal.

Software control

The scope of delivery includes application software that enables complete remote control of the PGA 1241 via the USB interface. Integration into existing automated test systems is made possible by disclosing the interface commands.

The amplifier can be configured so that it automatically switches on again after a pre-programmed time (1 - 255 s) in the event of power loss or overcurrent shutdown.
