TT7000
PC Control Application – Meter / Counter Mode
In Power Meter / Counter Mode, when the RUN-STOP button is pressed the TT7000 meter application will
continuously display live data from the device and build a history graph to the right
As with the signal generator, the counter reference frequency source can be changed to external if needed. Auto
detect is recommended in most situations. A high quality external reference can increase the counter accuracy.
The TT7000 Wideband Power Meter uses the internal frequency counter to calibrate itself. If the input signal
power level is too low and the counter cannot successfully determine the correct frequency, the power meter
accuracy will significantly degrade. In this case the user should enter a manual calibration frequency.
The frequency counter gate time and power meter averaging can be adjusted to the user s preference. Slower
update rates average more readings over a longer time, and will result in a more accurate measurement.
A green background inside the meter display indicates a good value. Orange indicates that the signal is either too
weak to count or measure, or that it is not consistent. Red indicates that the power level is over the maximum
readable input level.
