87236 Series USB Peak/Average Power Sensor (50 MHz to 67 GHz)

The 87236 Series USB Peak/Average Power Sensor is a broadband power measurement instrument that uses a USB 2.0 interface to enable average and pulse power measurements, as well as CCDF statistical analysis. It has a frequency range of 50 MHz to 67 GHz, with maximum average power measurement accuracy o f 0.20 dB, a video bandwidth of ≥30 MHz and rise/fall times of ≤13 ns.

This compact and lightweight product utilises USB power and communication for connection to a computer. It can be used to expand the power measurement capabilities of electronic measur ement instruments and test systems, making it suitable for field testing, production line testing, and system integration.

Key Features

• The 87236 Series features average power measurements down to -45dBm and pulse envelope measurements down to -35dBm, with average power measurement accuracy up to  ± 0.20dB. It supports external triggering in average only mode. By adjusting aperture size and trigger delay, users can select any portion of the waveform for measurement
• The 87236 Series accurately measures both power and timing parameters of pulsed signals. With a maximum video bandwidth of 30 MHz and rise/fall times of 13 ns, it can measure puls es with widths down to 50 ns
• The 87236 Series enables internal zero calibration of Power Sensors via internal switching circuits when connected to the device under test. This accelerates measurement speed, reduces connector wear, and lowers measurement un certainty
• The 87236 series incorporates a built in trigger input function. Using the standard trigger cable, external trigger signals from the signal source or device under test can be connected to the Power Sensor , enabling precise triggering of small si gnals approaching the lower limit of signal
  noise
• The auto measurement function allows users to obtain measurement results with a single button press when measuring pulse modulated signals
• Auto measurement covers 16 pulse power and timing parameters
• Power parameters: Peak power, minimum power, average power, top power, bottom power, peak to average ratio, overshoot, pulse rise/fall time
• Time parameters: Pulse width, pulse period, pulse frequency, edge delay, rise time, fall time, duty cycle, off time
• The 87236 series achieves measurement speeds of up to 50,000 readings per second in buffer mode
• Pre-set functions enable direct access to measurement configurations for 23 common wireless communication formats, including GSM900, EDGE, NADC, iDEN, Bluetoot h, CDMAOne, and CDMA2000, reducing user setup time
• External trigger buffered measurement mode allows customization of measurement sequences based on test requirements. Results are cached in real-time and can be retrieved after completing the entire sequen ce. This mode is typically used for: power sweep measurements; step frequency sweep measurements; list measurements based on communication signal time slots and frame structures
