Features
● 1ns Settable Display Resolution
The ML2490A has 1ns settable resolution on time based
measurements from 50ns to 3.2 µs.
● 50ns minimum time display
See and measure the detail on narrow pulse width signals.
● 8ns typical Rise time with MA2411B sensor
The ML2490A rise time is typically 8ns with the MA2411B
pulse sensor providing a fast measurement on the most
demanding of radar signals.
● 65MHz Bandwidth
The power meter mainframe has 65MHz bandwidth.
Wide enough for accurate rise time measurements on
radar signals or for measuring the peak signal of the latest 4G OFDM signals.
● Two Sample modes
For time durations up to 3.2 µs, the ML2490A series samples continuously. This can be set either automatically or the
sample rate can be adjusted directly by the user.
For time durations of 50ns to 3.2µ s the power meter uses repetitive sampling to build up the trace to 1ns settable
display resolution. Changeover between the two modes is automatic.
● External Video Connector
The ML2490A has a video connector on the rear panel as standard. The power meter can be connected to a standard
CRT 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.
● 50MHz and 1GHz Calibration signals
The ML2490A has 50MHz and 1GHz calibrators as standard. Frequency is automatically selected for the sensor
in use.
● Dual Display Channel
The ML2490A supports 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.
It can be switched between display channels quickly and simply via the Ch1/Ch2 Hard 'hot' key on the front panel.
The user can also choose to view the measurement results as a graph profile or numerical readout.
● Measurement Gates
At the heart of the power meter's signal processing lies the measurement gate facility. The new power meter supports
up to 4 independently set gates or 8 gates repeated in a pattern. The gate allows the user to capture the relevant
information from the signal under test. The wide bandwidth and high speed A/D allows the positioning of the gate
very accurately within the signal profile. The user can choose between several measurements performed within the
gate, average, peak, crest, max and min.
The max and min data are time stamped so that the position of these signals is recorded within the gate and can be
used to record the overshoot and undershoot of a pulsed signal.
● Markers
4 independent markers are available for denoting points of interest on the signal profile. The active marker can be
scrolled directly from the front panel. A delta marker can be set independently from the active marker to read the
difference or the average power result. The delta marker function can be linked to provide continuous scrolling
through the signal.
● Special Marker features
A set of specialised automatic marker functions has been provided to ease the measurement of pulsed systems.
These functions are automatic pulse rise time, pulse fall time, off time and pulse repetition interval.
● Trigger facilities
High speed measurements require precise triggering therefore the trigger level can be set manually or automatically.
The ML2490A series offer the following trigger modes:
Continuous, internal trigger on the rising or falling edge of either input A or input B and external TTL trigger.
The external trigger allows the power meter to be synchronised to external equipment. Data collection can be
delayed for a pre-determined time after the trigger point. The internal trigger facility incorporates a settable frame
arming facility which enables the power meter to synchronise to multi-pulse signals. A pre-trigger facility allows the
capture and display of information on the signal before the trigger.
The single shot trigger facility can be used to capture specific one off events with a bandwidth of 20MHz.
Long duration pulses can also be measured in CW mode and the trigger sensitivity extends to <-30dBm.
● Test Limits
The ML2490 series has two different types of automatic test limits. For many applications a simple power limit can
be set up to test the upper and /or lower boundaries of the signal. For pulsed systems such as RADAR a time varying
limit line can be set to test all aspects of the pulse profile. The power meter can be set up to indicate pass or fail and
to hold the measurement display on failure which is important when trying to track down intermittent faults.
An internal limit editor enables the user to create and select his or her own limit profiles.
● Presets
The ML2490 offers a number of radio system presets. Each preset configures the power meter settings to measure
a radio system. GSM, GPRS, WCDMA, WLAN, Bluetooth and radar are some of the examples of radio systems
supported by this facility.
● Settings stores
The power meter has 20 settings stores. These provide a convenient way of having application specific measurement
set ups for easy recall by the user.
● Remote Interfaces
The ML2490A series supports GPIB and RS 232 as standard.
● Secure mode
The ML2490A series has a secure mode for operations in security sensitive areas. Once activated the secure mode
wipes all information stored in the non-volatile RAM on power up.
● CW Meter Mode
Functions as a dual purpose high accuracy, high dynamic range CW power meter

The high bandwidth and sample rate of the ML2490A provide accurate peak measurements on a variety of RADAR, Radio-navigation
and Radio-location systems.
The ML2490A series has a number of features tailored for peak
power measurement on pulsed systems.
With a typical 8ns rise time, and a 1ns resolution on the measurement, the ML2490A and MA2411B have the performance to look at
the rising edge of radar signals.
The power meter can be easily set up to trigger on a pulse or
sequence of pulses. Up to 4 independent gates can be set to measure the average, max and min powers on a sequence of pulses. The
data for the max and min includes the timestamp and gives the user
automatic display of the position and value of the maximum
overshoot and minimum undershoot in each pulse.
A set of automatic marker functions gives pulse rise time, fall time,
off time and Pulse Repetition Interval.
The Delta marker can be set up to measure the droop of the pulse top.
The Trigger event display is available as either arrows on the border of the screen or as an adjustable trigger event waveform on
the display.
All timings for the gates and markers are taken from the trigger
event.
The offset table function corrects the power meter reading to read
the true output power when the power meter is being used with a
coupler or high power attenuator in the radar test system.
Radar Systems

The ML2490A has been designed to measure the peak power of
wideband OFDM systems currently under development . The display can be configured to measure Average, Peak and Crest
Factor.
Dithered sampling ensures accurate measurements on wideband
high data rate carriers under continuous transmission.
The 65MHz mainframe bandwidth enables high accuracy peak
measurements on the most demanding power envelope conditions.
A preset is available to instantly set the power meter up to measure continuous OFDM.
CCDF, CDF and PDF statistical functions are supported on the
OFDM measurements and enable the designers of power amplifiers to correctly estimate the margins on the peak power handling
capabilities of the amplifiers.
PAE, Power Added Efficiency can be measured on the dual input
ML2496A. Amplifier Bias Voltage can be entered manually or over
the GPIB. Bias current can also be measured using a current
probe connected directly to the power meter.
Wideband OFDM Signals

A Power Sensor for every application
Anritsu manufactures 7 different families of power sensors, where each design has been optimised for
a specific application.
Power sensors are based on either thermal converters or diode detectors.
Diode power sensors are based on half or full wave diode rectifiers constructed from zero bias Schottky diodes.
The rectifier output is low-pass filtered forming an envelope detector. This post detection bandwidth is sometimes
referred to as the video bandwidth and is a measure of how quickly the power sensor can respond to a changing input
signal such as a Radar pulse or a multi-carrier OFDM signal.
The power meter has two modes, pulsed modulated and CW. Most sensors can work in either mode. The trade off
between the modes is dynamic range; increases of bandwidth are traded off for reduction in overall sensitivity.
The choice of sensor is dictated by several considerations, frequency range, dynamic range and the modulation.
The rise time of the sensor should be chosen to match the rise time of the modulation
● Pulse and Wideband Sensors:- MA2490/1A and MA2411B
The MA2490A and MA2491A sensors have been designed as dual purpose Wideband and CW sensors.
These sensors have a 18ns rise time in the pulse modulated mode setting on the power meter and can be used to
make average, peak and crest measurements on signals with rapid amplitude change such as WCDMA, WLAN,
WiMax and Radar. These sensors have a video bandwidth of 20MHz. These sensors have a built in CW mode, there
is a FET switch which chops the signal from the sensor at low power levels when CW mode is selected on the
power meter.
The pulse sensor MA2411B has been specifically designed for the widest possible bandwidth. This sensor has the
fastest rise time and does not contain a FET switch for low level CW applications. Use this sensor for the most
demanding rising edge measurements and wideband measurements on OFDM multi-carrier signals.
● Standard Diode Sensors:- MA2470D
The MA2470D series Standard Diode Sensors have been designed for high dynamic range, high accuracy CW and
TDMA measurements. The sensors have 90dB dynamic range and linearity better than 1.8% making them the choice
for precision measurements. The rise time of these sensors is fast enough for power measurements on GSM and
similar TDMA systems that use GMSK modulation.
● High Accuracy Diode Sensors:- MA2440D
The MA2440D series high accuracy diode sensors have a built in 3dB attenuator to minimise input VSWR. They are
used where the best measurement accuracy is required over a large dynamic range, for example when measuring
amplifiers. High accuracy diode sensors have a dynamic range of 87dB compared to the 90dB of standard diode
sensors. In all other respects the performance of the sensors is identical to the standard diode sensor.
● Universal Power Sensors:- MA2480D
The MA2480A series universal sensors are true RMS sensors that have a dynamic range of 80dB. These sensors
can be used for average power measurements on multi-tone or WCDMA signals. The sensor architecture consists
of three pairs of diodes, each one configured to be working in its square law region over the dynamic range of the
sensor. Anritsu's three stage approach leads to a faster measurement as the signal to noise ratio is better than earlier
two diode pair architectures.
Option 01 provides TDMA measurement capability. This calibrates one of the diode pairs for linearity over a wide
dynamic range.
● Fast Thermal Sensors:- MA2420D
Anristu's thermal sensors provide excellent power measurement accuracy over 50dB dynamic range with more
speed than any other thermal sensor available. Thermal sensors measure the true RMS power regardless of the input
waveform, so are suitable for measuring the power of a variety of continuous waveforms such as WCDMA,
multi-tone signals and CW. The MA2420D series have excellent linearity and low VSWR, making them good choices for laboratory applications. The thermal power sensor includes a version without a DC block which can measure
down to 100KHz.

50MHz Reference Oscillator
When power sensors must be
located a long distance from the
power meter, the MA2418A
Reference Oscillator provides a
remote, traceable 0dBm power
reference.
MA2418A is DC powered from a
16 to 24 volt jack plug.
Bail Arm & Protective
Front Cover
A bail arm is available as a
convenient carry handle and is
suitable for angling the meter
on a workbench.
The ML2430A Series Power Meters combine the advantages of thermal meter accuracy, diode meter speed and
peak power meter display graphics.
The result is a single instrument that samples at more than 35k per second and achieves 90 dB dynamic range with
a single sensor.
The ML2430A Series includes graphics display capability as a standard feature. The ruggedised housing and optional
high-capacity NiMH battery bring laboratory quality accuracy to field service applications.
ML2430A Series
Power Meters Ideal for CW applications
ML2419A Range Calibrator
Reduce annual calibration
expense with Anritsu’s precision
range calibrators.
The ML2419A Range Calibrator
verifies the ML2400A Series
Power Meter’s measurement
channels.
The meter’s 50 MHz Oscillator
level is verified by comparison
method. When the calibrator is
connected, user operation
prompts appear on the meter’s
screen.
Soft Carry Case
The soft carry case protects the
power meter and has pockets
for all common accessories
making it the ideal carry bag for
field use.
