There is no 18 GHz handheld spectrum analyzer model with tracking generator.
The pass-through power sensor FSH-Z44 will expand the capabilities of the device in measuring strong signals. With this transmitter it is possible to measure levels up to 120W (300W unmodulated carrier). Frequency range 200 MHz - 4 GHz. The result of the measurement is the incident and reflected power values. ( Cm. FSH specification)
The absorption power sensors FSH-Z1 and FSH-Z18 have a wider frequency range. These measuring heads can measure powers up to 8 GHz (for FSH-Z1) and 18 GHz (for FSH-Z18). ( Cm. FSH specification)
Measuring attenuators (available as an option from Celtec) allow you to measure power over a very wide range.
