Specifications
Specifications
All specifications are guaranteed unless labeled Typical. Typical specifications are provided for your convenience.
NOTE. Warranted characteristics that are checked in the Performance Verification are marked with a
 symbol.
The performance limits in this specification are valid for the following conditions:
The VectorVu-PC software version is 1.0 or greater.
You operate the instrument in an environment that meets the temperature, altitude, and humidity characteristics listed in
these specifications.
You allow the instrument to warm up sufficiently (> 30 minutes). To do this, connect the instrument to a PC and start
the VectorVu-PC application. The application must be continuously acquiring data for at least 30 minutes. Once the
instrument has warmed up, the thermometer indicator in the instrument status bar changes from yellow to green.
NOTE. The TTR500 does not fully power on until VectorVu-PC has established communication with the TTR500 and is
acquiring data.
For small signal S-parameters, the instrument must have been calibrated using the recommended precision calibration
kit at an ambient temperature within ±1°C of the current ambient temperature.
All specifications are valid in the temperature range of 18°C to 28°C unless specified otherwise.
