ATF20B the DDS function signal generating device uses the digital synthesis technology, has completes the high performance target which and the numerous function characteristics fast the surveying work needs. Its simple, but the function defined front panel design and/English liquid crystal display interfacial energy enables you to be advantageous for the operation and the observation, chooses a function expandably, may enable you to obtain the enhancement the system performance.

  This is one independent part which has nothing to do with the instrument, its input end connects on the rear panel “the power amplifier input” the plug, the out-port connects on the rear panel “2 time of power amplifier outputs” the plug. When use with a testing cable line, the input signal will connect “the power amplifier input” the port, “2 time of power amplifier outputs” the port namely may obtain the process 2 time of power amplification signal in the rear panel. The input signal may be this aircraft's output A, outputs B, may also be other instrument's signal.
  

Power amplifier's voltage amplification factor is two times, the maximum output scope is 22Vpp, therefore the biggest input scope should limit in 11Vpp, when surpasses the limit, the output signal will have the distortion.

Power amplifier's frequency range is 10Hz~150kHz, within this scope scope smoothness surpasses 3%, the sine wave degree of distortion surpasses 1%, the upper frequency may achieve 200kHz.

Power amplifier's output expression is: P=V2/R; In expression: P is the output (unit is W), V for the output amplitude effective value (unit is Vrms), R is the load resistance (unit for OMEGA) the maximum output scope may achieve 22Vpp(7.8Vrms), the minimum load resistance may slightly arrive 2?, in addition the working conditions temperature is higher, the output signal frequency is higher, the request output signal degree of distortion is smaller, possibly achieves the peak power output is smaller, in the ordinary circumstances the peak power output may achieve 7W (8?) or 1W (50?).

Power amplifier has the output short circuit protection and the overheated protection, generally will damage, but should avoid the long time output short circuit as far as possible. The frequency, the scope and the load do not need to use to the limit the limiting value as far as possible, specially two kind of parameters cannot simultaneously use to the limit the limiting value, in order to avoid causes the damage to power amplifier's performance.
