Diode pulse limiter with built-in 10 dB high power attenuator and fuse lamp to protect sensitive measuring equipment when measuring spectra with high energy. Thanks to the built-in fuse lamp serious overload situations of sensitive equipment can be recognized fast and reliably. A replacement bulb is placed inside the unit. The pulse limiter prevents expensive equipment defects. The very flat frequency response allows high measurement accuracy, even if only a few sample values are used for correction.

Advantages.
Compared to other pulse limiters the VTSD 9561 F has the following advantages:
- The limitation process is visible by a glowing of the bulb. A glowing bulb means that the measurement result is invalid because it is based on intermodulation and phantom spectra.
- Extreme high levels of disturbance voltage destroy the bulb and not the limiter itself. The connection to the receiver input will be interrupted and the meter is well protected. Only the bulb has to be exchanged. One spare bulb is enclosed inside the housing which may be opened for this purpose. Further spare bulbs can be ordered from us. When ordering please tell us the serial number of your VTSD 9561 F since the high frequency properties of the bulb do influence the attenuation of the limiter. We deliver selected and specially for your S/N assorted spare lamps.
- On request we can assemble various connectors to the in- and output e.g. N-female, N-male, BNC-female, BNC-male.
