PM1890 RF and Microwave Wideband Power Sensor / Meter

The PM1890 is compact power sensor/meter that deliver fast, accurate RF and microwave power measurements. A broad range of CW and pulse modulation measurements are available. The sensor comes with Virtual Power Meter application software for controlling the meter, displaying readings, and recording data. The combination of the sensor/meter and PC provides a complete solution, eliminating the need for a separate, dedicated meter mainframe. By communicating with the Power Sensor the program covers a wide range of applications. Besides the basic continuous average measurement function, Virtual Power Meter application also includes the measurement modes timeslot, burst and scope measurement. The PM1890 sensor is highly accurate standalone measuring instrument. With its internal CPU the Power Sensor processes the measurement results and communicates directly with a PC via an USB connection. With a high dynamic range and automatic error correction the power sensors are suitable for nearly every measurement task. As an example, among other duties, the PM1890 is able to measure pulse parameters automatically, and the Virtual Power Meter software represents the results.For measurements of any number of GEM Microwave’s USB power sensors the graphical user interface of the Virtual Power Meter application offers functionality and operation comparable to a multichannel oscilloscope.

KEY PERFORMANCE SPECIFICATIONS:
• Frequency range 50 MHz to 18 GHz, (50 MHz to 500 MHz with reduced video bandwidth)
• N Connector
• Peak power measurements of radar and mobile communications signals with up to 40 MHz RF video bandwidth; sensor rise time <10 ns
• Automatic burst detection and acquisition
• Ultra-fast statistical analysis (one-million point CCDF within <20 ms)
• Accurate continuous power measurements on modulated and unmodulated signals in the range from –63 dBm to +23 dBm
• High measurement repeatability due to very low zero drift of <125 nW for single-shot events and statistics, <1.5 nW for repetitive measurements
• Uncertainty as Low as 2%
• Operation via USB on a Laptop/PC
• Ideal for radar applications
• Readings Rates up to 15000 Readings/s (buffered mode)
• Automatic pulse analysis
• Statistical analysis
• High resolution mode
• Trigger master mode
• Two-year warranty

Features:
• Outstanding dynamic range and accuracy. Signal details can be analyzed in the range down to –50 dBm. Continuous average power measurements are even possible in a dynamic range of 86 dB (–63 dBm to +23 dBm). The PM1890 sensor fulfils practically any accuracy requirements. A complete sensor characterization over the entire temperature range produces excellent stability.
• High-speed data acquisition. Using a single-shot bandwidth of 100 Msample/s and a video bandwidth of 40 MHz, it is possible to measure pulses with a width of only 50 ns. The time resolution can be increased to up to 500 ps/div for repetitive pulse sequence. The fast rise time of typ. 10 ns enables accurate determination of the peak power both for the standard signals used in mobile communications nowadays and for the proprietary pulse sequences that are common in military applications, for example. Due to the high trigger sensitivity of typ. –25 dBm to +23 dBm (at 40 MHz video bandwidth), automatic recording of measured values is ensured for the usual signal levels.
