YC-TI-PS-0002 | Ceyear 87235 Series USB Average Power Sensor
Price on request
Request a quoteThe 87235 series measures average power of CW, pulse-modulated and vector-modulated signals via USB 2.0. Eight models cover different frequency and power requirements; the 87235DG provides a −50…+44 dBm measurement range.
Series appearance reference showing multiple models. It does not imply that a set of sensors is included. The supplied model and connector are defined in the quotation.
