External Video Connection The ML2490A is the latest addition to the Anritsu Peak Power meterline and extends the performance of the successful ML2480A series for the most demanding high bandwidth peak power measurement applications. This new instrument incorporates extra wide bandwidth and a high resolution sampling system to provide detailed informa- tion on the power profile of Radar signals and the latest generation of wide bandwidth OFDM 4G systems. The ML2490A series supports all the functionality of the ML2480A series and offers in addition a mainframe bandwidth of 65 MHz and an 8 ns rise time with the MA2411B Pulse sensor. The ML2490A has a high-resolution sampling scheme that samples the signal at up to 1 ns settable resolution, offering the user the abil- ity to look at fine detail on the power envelope. The ML2490A series has been designed to use the MA2411B Pulse sensor and the MA2490/91A wideband sensors. The ML2490A is ful- ly compatible with the wide range of Anritsu diode, fast thermal and universal sensors. The power meter also offers a high performance CW mode creating a truly universal power meter for all applications. Graphical or Numerical Results can be selected and displayed. Acomprehensive GPIB command set gives a wide range of com- mands to extract data from the signal under test. A variety of built-in processing functions such as gates and markers enable precise sections of the signal to be measured and analysed using different processing functions. Two versions of the product are available: The ML2495A Single sensor Input version and the ML2496A, the dual sensor input version. The ML2496A can be used for measuring gain under pulsed conditions. Title Flexible Display offers Single or Dual display output.

Features

•

1 ns Settable Display Resolution µ s. The ML2490A has 1ns settable resolution on time based measure- ments from 50 ns to 3.2

•

50 ns minimum time display The ML2490A can be set to measure narrow pulse width signals.

•

8 ns typical Rise time with MA2411B sensor The ML2490A rise time is typically 8 ns with the MA2411B pulse sensor providing a fast measurement on the most demanding of radar signals.

•

65 MHz Bandwidth The power meter mainframe has 65 MHz bandwidth. Wide enough for accurate rise time measurements on radar signals or for measur- ing the peak signal of the latest 4G OFDM signals.

•

Two Sample modes µ s the power meter uses Repetitivesampling to build up the trace to 1ns settable display resolution. Changeover between the two modes is automatic. For time durations up to 3.2 µ s, the ML2490A series has a continu-ous sample rate. This can be set either automatically or the sample rate can be adjusted directly by the user. For time durations of 50 ns to 3.2

•

External Video Connector The ML2490A has a video connector on the rear panel as standard. The power meter can be connected to a standard VGA monitor. The power meter can be located remotely in a test rack and the video screen located close to where the adjustments are taking place.
