Features
Ease of operability
Both the ML248xA and ML249xA incorporate a host of features to make setup and
operation as simple as possible. There are predefined and configurable presets, 20
settings stores, multiple independently or repeated gates, 4 independent markers for
denoting points of interest on the profile, and user configurable templates.
Dual channel display
Both the ML248xA and ML249xA support dual display channels. Each display channel is
a measurement set up and can use any selection or combination of the sensor inputs.
The instrument can be configured to view one display channel or two and can be switched
between display channels quickly and simply via the CH1/CH2 hard key on the front
panel.
Large colour display with graphical MMI
The quarter VGA high-resolution colour display is ideal for profiling and other complex
sequences.
Video output
The ML249xA has a video connector on the rear panel as standard and 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.
Enhanced Measurement Bandwidth
On the ML248xA, the 20 MHz bandwidth is ideal for accurate WLAN, WCDMA and Radar
measurements, and removes the need for post-measurement accuracy calculations. On
the ML249xA, the mainframe has 65 MHz bandwidth that is wide enough for accurate rise
time measurements on radar signals, or for measuring the peak signal of the latest 4G
OFDM signals. The ML249xA settable resolution on time based measurements from 50ns
to 3.2µs is 1ns
Two sampling modes
For time durations up to 3.2 µs, the ML249xA has a continuous 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 µs the power meter uses random repetitive sampling to build up
the trace to 1 ns settable display resolution. Changeover between these two modes is
performed automatically.
High speed sampling
Sampling of up to 64 MS/s (ML248xA) / 62.5 MS/s (ML249xA) is ideal for WCDMA, Radar,
EDGE, and WLAN measurements.
Compatibility
The power meter is compatible with all MA2400A/B sensors used on the existing Anritsu
power meter range.
Remote interface
The ML248xA and ML249xA support both the GPIB and RS232 interfaces.
Secure mode
The power meter has a secure mode for operations in security sensitive areas. Once
activated, the secure mode erases all information stored in the non volatile RAM on power
up.
