Description
The ML2437A Power Meter combines 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. This meter includes graphics display capability as a standard feature. The ruggedized housing and optional high-capacity NiMH battery bring laboratory quality accuracy to field service applicati***. ML2437A has one input.
The following Sensors can be used with the ML2437A Power Meter:
MA247xD Standard Diode Power Sensors
MA248xD Universal Power Sensors
MA244xD High Accuracy Diode Power Sensors
For portable USB power measurements see MA24106A
Applicati*** needing a wider bandwidth power should also c***ider the ML2487A/88A or ML2495A/96A power meters.
Features
Speed and dynamic range
The 90 dB range MA247xD Series Power Sensors’ high sensitivity reaches stable power readings to -70 dBm. 35 kHz sample rates profile cellular, PCS and other pulsed signals to 0.1 msec resolution. Modern connector technology achieves industry leading return loss for improved accuracy through 50 GHz. The 87 dB range MA244xD Series High Accuracy Sensors further improve return loss performance by adding a matching circuit to the MA247xD Series’ front end.
Fast thermal sensors
Anritsu’s latest semiconductor processing technology produces thermal power sensors with speed increased by an order of magnitude. Improvements in connector technology reduce measurement mi***atch uncertainty through 50 GHz to levels previously attained only to 20 GHz. The fabrication technique as well as the ML2430A Series' sampling and DSP technology optimize measuring speed to 4 ms rise and fall times.
GPIB speed
Industry leading speed is achieved under a variety of operating conditi*** including ***eraging settings, sensor control settings, triggering conditi***, operating mode, sensor type, and GPIB interface manufacturer. The ML2430A series offers the ability to measure and transfer a high speed burst of 200 data points using profile operating mode with sampling rates of 35k per second.
GPIB emulation
With 99.9% emulation of older meters, the ML2430A series improves ATE system productivity. Typical test system speed improvement is 2 to 10 times faster system speed depending upon the number of measurements taken during the test, the minimal use of wait statements within the code, and the meter model emulated.
Triggering controls
What use is high speed without triggering and sample controls? Data acquisition event arming and triggering functi*** traditionally found on expensive peak power meters are standard in the ML2430A series. Triggering delay and the sample integration time per reading can be directly controlled by the operator. Trigger sources include, continuous, internal, external TTL, and manual. Thus, data acquisition can be optimally controlled for synchronization with other test equipment.
Burst profile graphics display
The ML2430A features random repetitive sampling for high resolution of fast signals. A time domain graphic display profiles pulsed signals over a power range of –40 dBm to +20 dBm. 35 kHz sampling speed produces clear power profiles of cellular and PCS signals including TDMA, PHS, G***, and DCS-1800. Pulse-top power is easily and repeatably measured using between cursor ***eraging. Measure pulse-top power over >80 dB dynamic range in readout mode at GPIB speeds >200 readings per second.
Power vs. time graphics display
One of the most common power meter ATE program types is a plot of RF power versus some stimulus. The power versus time mode is a strip chart style display for monitoring gain and output power variati*** over time/temperature, supply voltage or a component tolerance. In service applicati***, power versus time mode speeds trouble shooting of unusual conditi*** such as intermittent switches or abnormal power control in a mobile telephone. The power versus time mode provides a clear strip chart display of RF power variation.
Parallel printer connector
Many deskjet series printers can be connected directly to the ML2430A Series for fast documentation of performance on the bench or in the field. Meter calibration, triggering and ***eraging settings are listed with the display printout. Thus, evidence of DUT (device under test) anomalies can be duplicated quickly, allowing engineers to fix problems with minimal time investment.
Additional Specificati***:
90 dB dynamic range
Typical communicati*** industry ATE systems operate over a 60 to 80 dB dynamic range. The MA247xD Series' 90 dB dynamic range replaces two 50 dB sensors. Further an RF switch is no longer needed for the two sensors. This reduces software control complexity and further speeds test execution.
Sensor EEPROM
All MA24xx Series sensors are equipped with internal EEPROMs for storage of calibration factor data vs. frequency. This allos the power meter to interpolate and correct readings automatically, improving accuracy and convenience.
High reliability
Rugged poly-carbonate chassis design handles drop shocks and rough field treatment. No vent holes are present, thus the meter is splash resistant. A front cover panel and softcase are optional for further environmental protection. Power sensors are also ruggedized for rough handling.
Improved accuracy
Mi***atch uncertainty is typically the largest source of error. The MA24xx Series Power Sensors offer a typical 5 to 6 dB improvement in sensor return loss, typically cutting mi***atch uncertainty in half. The MA244xD series High Accuracy Sensors incorporate a matching pad which further improves return loss by 5 to 6 dB - again halving mi***atch uncertainty.
Offset table for path loss correction
Compensating for the true frequency resp***e of attenuators, couplers, cables, switches and other test setup devices improves measurement accuracy. For this reason, the ML2430A Series can apply an offset table of attenuation-versus-frequency in addition to the traditional fixed dB offset capability. When a power sensor connection is preceded with a new 1N series wideband power limiter, the offset table compensates for frequency resp***e. Thus, the combination achieves an accurate, “burnout-proof” sensor.
Softkey menu control
Softkey menus simplify instrument control by making the user interface easier to understand. The numerical keypad simplifies the operator interface.
Battery
The optional NiMH “***art” battery supports high charge density for a typical 8 hour day of operation. Accurate fuel gauging, <2 hour fast charge cycling, and the elimination of NiCd style memory effect fur-ther enhances the convenience of this battery technology.
Voltmeter
The ML2430A Series also supports high speed voltage measurement. A rear panel BNC measures voltage or operates as V/GHz input supporting automated sensor calibration factor correction.
