Specifications
Specifications are valid under the following conditions: the instrument is within the calibration period, is stored for at least two hours at 0ºC to 50ºC temperature, and is warmed up for 40 minutes. Unless otherwise noted, the specifications in this manual include the measurement uncertainty.
Typical (typ.): characteristic performance, which 80 percent of the measurement results will meet at room temperature (approximately 25ºC ). This data is not warranted and does not include the measurement uncertainty.
Nominal (nom.): the expected mean or average performance or a designed attribute (such as the 50 Ω connector). This data is not warranted and is measured at room temperature (approximately 25ºC ).
Measured (meas.): an attribute measured during the design phase which can be compared to the expected performance, such as the amplitude drift variation with time. This data is not warranted and is measured at room temperature (approximately 25ºC ). NOTE: All charts in this manual are the measurement results of multiple instruments at room temperature unless otherwise noted. The specifications (except the TG specifications) listed in this manual are those when the tracking generator is off. |
