Specifications

Specifications are valid under the following conditions: the instrument is within the calibration
period; stored for at least two hours at 0℃ to 50℃ temperature; 40-minute warm-up. Unless
otherwise noted, the specifications in the manual include the measurement uncertainty.

• Typical (typ.): typical performance, which 80 percent of the measurement results will meet at

room temperature (approximately 25℃). The data are not warranted and do not include the

measurement uncertainty.

• Nominal (nom.): the expected mean or average performance or a designed attribute (such as

the 50Ω connector). The data are not warranted and are measured at room temperature

(approximately 25℃).

• Measured (meas.): an attribute measured during the design phase which can be compared to

the expected performance, i.g. the amplitude drift varies with time. The data are not warranted

and are measured at room temperature (approximately 25℃).

Note: All charts in this manual are the measurement results of multiple instruments at room temperature unless otherwise
noted.
