TT7000 

– Introduction to a Compact Multi-Purpose RF Instrument

 

The TT7000 combines a Microwave Frequency counter, Power Meter, 
Signal Generator, and RF divider in one compact instrument. This 
instrument can either be used as a stand-alone device, or operated from a 
PC via USB. The Frequency Counter and Power meter cover the band from 
100 to 7000MHz. The Signal Generator covers from 300 to 9600MHz.

The TT7000 is very simple to setup and begin to use. Stand-alone usage 
only requires a standard 5 volt USB type-C cable. This can be powered 
from a USB port on a PC, powered USB hub, wall charging adapter, or a 
lithium-ion battery pack. No data connection is needed. Once the device is 
powered, the TT7000 will display the firmware version and model number. 
The TT7000 will then boot up into Meter-Counter Mode and begin 
displaying the detected RF power level and the constant wave frequency.
