Portable generator ARINST ArSiG-S generates high-frequency signals in the range 1-6200 MHz. The device is capable of sweeping the output signal, both in frequency and in level. The generator has the ability to use an external highly stable signal source as a reference.
ARINST ArSiG-S generates sinusoidal oscillations over the entire operating frequency range.
The generator is intended for outside works. It is designed in a durable aluminum case in the form of a mobile device with autonomous power supply and is intended primarily for work directly on the object, since with low weight and compact sizes differs by low power consumption. The device is used to generate test signals for developing and debugging various devices: amplifiers, filters, receiving and transmitting paths, when measuring and analyzing antennas. In addition, the device is ideal for workshops, radio amateurs, educational institutions and laboratories.
The device has 4 "color resistive screen for convenience of setting up and control the instrument.

1 The measurement is performed after warming up the device for at least five minutes. The change in ambient temperature from the moment of calibration to measurements should not exceed ± 3°С.
2 When connecting the device to a charger with an output current of at least 3A.
3 If your PC has a limit on the maximum current supplied to the USB port, the device will automatically limit the maxi-mum charging current according to the current USB specification.
4 At an ambient temperature of 20±5°C after the battery is fully charged.
