4 Anritsu ML2438A-Partially Operational-with Extra Power Supply ModulesIf you own an ML 2437A or ML2438A this is a great price to have an upgrade or spare Analyzer!
You will have to transfer your good power supply module (they plug in, about 15 minutes work)
You are buying 1 to 4 Anritsu ML2438A Analyzers. See below for what is included. NOTE:
None
of these ML2438A analyzers are in working condition as delivered.
They are “As-Is” and may not be returned.
They have all been tested with a working power supply and have been checked for proper operation with a working and accurate sensor. The critical Calibrator level and frequency have been checked and calibrated if needed. The +5V supply, which Anritsu wants calibrated to exactly 5.000VDC, +/- 2mV has been adjusted to within that spec.
New Power Supplies were available from Anritsu as of about 90 days ago, but please verify for yourself.
I recommend re-checking the 5V supply once a new or repaired power supply module is installed.
All the Analyzers are complete with an internal non-working power module and 1 non-working spare for parts or repair.
All are complete units.
First buyer gets to choose which one(s) he wants:
Pick one meter and one extra power supply by number and include these numbers in the purchase comments to me.
None of these Analyzers have handles and only #1 has factory feet.
#3 has all connectors on the rear panel.
Please review the photos for selection.
Only extra power supply #1 is totally complete.
#2 & 4 may be missing some hardware.
#3 has components missing.
As you can see from the photos, these Analyzers are in decent shape cosmetically, but please form your own opinion. 1 complete set of manuals is furnished to the 1st buyer, a mostly complete manual to the 2nd buyer and just the User manual is furnished to the 3rd buyer. Nothing else is included in the sale.
These Anritsu ML 2438A meters are compatible with a very wide range of Power Sensors which are available on eBay and elsewhere.
As a recently retired consultant, I must very reluctantly, sell off my Lab equipment.
This equipment was purchased for my own use.
From Anritsu:
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 applications. ML2438A has two inputs.
Specifications:
90 dB dynamic range
Typical communications 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
Mismatch 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 mismatch 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 mismatch uncertainty.
Offset table for path loss correction
Compensating for the true frequency response 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 response. 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 (Optional-not installed)
The optional NiMH “Smart” 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.
