The DS Instruments TT7000 RF Power/Frequency Meter combines a Microwave Power Meter, Signal Source, Frequency counter, and RF Divider in one compact instrument. The frequency counter and power meter cover up to 7000MHz. The signal generator covers from 300 to 9600MHz.
Counting and Power reading can be done simultaneously over the entire band. The power meter dynamic range is from -50dBm to +5dBm. Accuracy is typically +/- 1.0dB from 0dBm to -30dBm when the frequency count is valid. Frequency can be manually set for low power signals to calibrate the power reading value.
The SG function is fully synthesized with step size less than 10Hz using precision internal or external 10MHz reference. Adjustable output power from +10dBm to -20dBm is now standard for the TT7000 with 0.25dB steps! Signal generator and power meter can function simultaneously and will auto-calibrate to the set frequency.
The RF input can also be processed by a RF Divider with 1/2/4/8 options. The output of the RF Divider is available on the RF OUT port with adjustable power level.
With the DS Instruments TT7000 RF Power/Frequency Meter connected to a host PC via its USB port, which is configured as a virtual COM port, industry standard SCPI text commands can control the TT7000 and retrieve instrument measurement data. The OLED display and interface buttons allow the user to not only verify incoming SCPI commands from the USB interface, but also control the unit in standalone mode with NO HOST PC REQUIRED.
The TT7000 requires up to 0.75 Amperes in certain modes. Some legacy USB ports
are limited to 0.5 Amperes. A stable 5.0 volt input voltage is critical for reliable
operation within the unit s specifications.
Many common ways to satisfy this requirement exist:
*A High Quality USB cable uses a heavier gauge wire resulting in less voltage loss from end to end.
Our suggested cable is maximum 1 meter length with 22 AWG conductors.
