Attenuators And Pulse Limiters
A bidirectional attenuator, i.e. the attenuation and power capability specification is valid for both directions. There is a large variety of applications for this attenuator: The measuring range of a spectrum analyzer can be increased. Any kind of meter can be protected against overload; it can be used to control the linearity of a meter reading. It can minimize measurement uncertainty caused by mismatched impedances. During an EMI receiver calibration an attenuator directly at the pulse generator output is inevitable.

Step Up Transformer
MagD
SCOPE proudly introduces Step-Up Transformer - MagD, specially designed to cater the needs of testing of instrument Transformers. Before new systems are put into service or after any occurrence of fault, the instrument transformers need to be tested for their outputs. It is to be ensured that these instrument transformers are giving proper outputs to the protective relays. MagD is used to plot excitation curves for instrument transformers. Inbuilt voltmeter and ammeter, eliminates the need of external meters for plotting of curves. It can also be used for de-magnetization of transformer cores and also turns-ratio tests can be conducted using MagD.
