Specifications given for +25 °C unless otherwise noted. Specifications describe the instrument’s warranted performance. Supplemental characteristics (in italics) are

intended to provide information useful in applying the instrument by giving typical, but not warranted, performance parameters.

RF may leak through video connector especially below 1 GHz; if objectionable, this may be eliminated with low-pass filter.

SWR measured at 2 dBm.

Sensitivity decreases with increasing temperature typically 0.5 dB from 20 °C to +25 °C, 0.5 dB from +25 °C to +40v C. 1 dB from +40 °C to +55 °C, 1.25 dB from

+55 °C to +75 °C, 1 dB from +75 °C to +85 °C.
