Global Specialties 9004 4 Instrument Test Station, 1Hz to 1 MHz Frequency

The Model 9004 is great for service or Test bench and also for school labs. The touch of a button can select the 5 digit counter to accurately measure the function generator frequency, the RF generator frequency or an external i/p signal. The 9004 combines some most needed Test Equipment in a very special way. It effectively gives you a 1 Hz to 110 MHz generator and a 60W power supply to power your test circuits. The professional will find it covers a broad spectrum of his test needs and the schools will see plenty of experiments with it. A very wide variety of experiments in Analog, Digital and RF can be performed with just this unit. The unit is great for service or Test bench and also simple enough for a school lab. All functions are kept completely independent for full functionality and there is no clutter of switches and knobs. The RF generator covers a frequency range all the way up to the commercial FM band. It also has fixed internal AM and FM modulation and also the facility of external modulation. The function generator features unipolar square/pulse outputs to directly interface to digital circuits, in addition to the standard Sine, Triangle, and Square. There are 2 Outputs-50 Ohm and 600 Ohm to match audio impedances. 100 KHz to 110 MHz RF Generator. 1 Hz to 1 MHz function generator. Variable 32 V, 2A DC power supply with adjustable voltage and current limit. Digital readout for voltage and current. AM Signal: 100 KHz to 110MHz in 7 ranges and continuously variable over the whole range with a coarse and fine control. Modulation frequency: selectable 400 Hz/ 1 KHz.
