ML2480A Series
Wideband Peak Power Meters
Colour Graphics Display.
Up to 64 Ms/s sample rate
produces accurate profiles of
Radar, WCDMA, WLAN and latest
generation cellular systems.
Displays the peak, average and
crest factor of any input signal.
Softkeys.
Menu driven operation
simplifies test procedures.
High Reliability.
Rugged, splash resistant chassis
design handles drop shocks and
rough field treatment. A front panel
cover and softcase are optional for
further environmental protection.
Accuracy.
Excellent return loss sensor design
reduces typical mismatch uncertainty
by half - improving accuracy and
repeatability. Less SWR ripple in
measurement data improves
production yield and quality control.
Sensor EEPROM.
All MA2400A/B Series sensors have
built-in EEPROMs with factory
Calibration Factor data.
Six User Calibration Factor Tables allow
extra frequency points or compensation
for couplers and power attenuators.

The dual display channel gives complete flexibility and can provide
two different perspectives on the measurement.
Examine the pulses in detail and capture the entire pulse train.

The ML2480A supports dual display channels. Each display
channel can be set up to make a measurement and can use any
selection or combination of the sensor inputs. The instrument can
be configured to view one display channel or two. The instrument
can be switched between display channels quickly and simply via
the CH1/CH2 Hard 'hot' key on the front panel. The user can
choose to view the measurement results as a graph profile or
numerical readout.
Dual Display Channel
At the heart of the new 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 sampling allow 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 are
available as selections for the output.
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.
Exclusion zones within the measurement gate are also available. Termed “fences”, these can be used to exclude sections of the
signal from the measurement gate which is particularly useful for excluding mid-burst training sequences. Each gate has a
switchable fence associated with it.
Measurement Gates
Four 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 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.
Markers
High speed measurements require precise triggering. The ML2480A 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 before or after the trigger point. The trigger facility incorporates a settable hold-off facility that prevents the
trigger from being re-armed and re-triggering on a noisy signal. A pre-trigger facility allows the capture and display of pre-trigger
information on the signal. The single shot trigger facility can be used to capture specific one-off events.

The ML2480A 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, TDMA phone
systems or WLAN, a time varying limit
line can be set up 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.
Test Limits
The ML2480A offers a number of radio
system presets. Each preset configures
the power meter settings to measure a
radio system. GSM, GPRS, WCDMA,
WLAN and Bluetooth are some
examples of radio systems supported
by this facility.
Presets
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.
Settings stores
The ML2480A series supports GPIB and
RS232 as standard. USB and Ethernet
will be available as options.
Remote Interfaces
The ML2480A series has a secure
mode for operations in security sensitive
areas. Once activated, the secure mode
wipes all information stored in the
non-volatile memory on power up.
