By Product Category

If a ML2438A power meter is ordered with no side mounting hardware and then later I decide that I want to add a rack mount kit will the case have the holes for the rack mount kit?

No. The ML2430A series power meters require special top and bottom case for the rack mount option. If the rack mount option is not ordered at the time of purchase the power meter will not have these special cases. The cases must be changed as part of the rack mount retrofit.

The ML243xA power meter is giving a "cannot identify" or "cal at 0 dBm invalid" message with the MA248xD power sensor. Is there a problem with the power meter?

No, the ML243xA Power Meter needs to have firmware revision 3.10 or greater loaded when using the MA248xD sensor.  The latest firmware can be downloaded from the product page or software tab below.

Is it possible to get an Ethernet or USB port on my Peak Power meter (ML248x)?

At this moment in time, ML2480A-16 (Ethernet and USB) is not a supported feature on the ML2480A Series. Units that have been, and are currently being, shipped do not have the necessary hardware or software.

My ML2438A power meter screen is flashing on and off with a green background and no data is seen on the screen.

This unit likely is in need of repair. Please contact your local Anritsu Service Center.

Can the MA2444D power sensor accurately measure a CW signal only above -20dBm? My concern is that if I am measuring power above -20dBm with multiple carriers that the measurements will not be accurate. If this is so, do I need to pad the input to keep the signals below -20dBm?

The sensors must be in square law to get an accurate measurement. The exception would be if the carrier frequencies are very close to each other. Note: This sensor has a 3dB pad built in so up to -17dBm would be OK. Anything stronger than -17dBm and you would need an attenuator to stay in the square law region to keep your measurements accurate when in a multiple carrier environment.

What is the difference between the MA24xxD model sensors and the older A and B models?

New D-series Model Power Sensors were introduced in early 2005 and they replace the previous A, B and C series Power Sensors. The EEPROM used in the older A, B and C series sensors (except for the MA2411A, MA2491A and MA2492A) has been discontinued by its manufacturer. The new D-series sensors use the same EEPROM as the MA2411A, MA2491A and MA2492A sensors and because of this have the same power meter software version requirements. The D-series Power Sensors are supported by the recent release of rev 3.10 power meter software from EMD. The D-series sensors contain an EEPROM which is not compatible with previous versions of ML2430A/ML2400A software. However, the D-series sensors are compatible with all versions of the ML2480A power meter software. All power meters shipped from EMD after November 14, 2004 contain version 3.10 and are fully compatible with the A/B/C and D series sensors. Customers who received new power meters shipped after November 14, 2004 will not have to load new power meter software before they use a D-series power sensor.

Will the MA4001A calibrator work with ML2438A power meters?

No, this calibrator does not work with the ML24xxx power meters.



How can the ML24xxA be used in a Secure Environment?

Anritsu manufactures three families of power meters: the ML2400A/30A series, the ML2480A series, and the ML2490A series. This note details how information is stored on the power meters and how it can be removed for security purposes. All families have three different types of memory device in the power meter. Flash Memory: This contains the firmware for the main processor, the firmware for the DSP, the code for the FPGA (ML2480/90A series only), the instrument type, the options fitted and the serial number. It does not contain any user information or any variables generated during the execution of the code. ML2400A/30A has 1Mbyte, ML2480A has 2Mbyte, and ML2490A has 2Mbyte of Flash Memory. The user cannot write to this memory directly, and this memory is not accessible by the user. Volatile Static RAM: This contains the DSP execution code variables. This is initialized on power up and wiped clean when powered down. For the: ML2400A/30A (it is) Internal to DSP ML2480A (it is) 1Mbyte + internal DSP memory ML2490A (it is) 1Mbyte + internal DSP memory The user cannot write to this memory directly, and it is completely cleared during power down. This memory is not accessible by the user. Non-volatile Static RAM: This is a battery backed static RAM, which is used to store both the current instrument set-up, saved instrument set-ups and the main processor code execution variables. All of the user set parameters, such as the frequency used for the cal factor, the trigger time, and which sensor is connected, are stored in these set-ups. The following are the memory sizes for NVRAM in the associated power meter: ML2400A/30A 512Kbyte ML2480A 1Mbyte ML2490A 1Mbyte The user cannot write to this memory directly, but it can be completely cleared using the secure mode procedure (see operating manual or below description). The user can store and retrieve instrument set-ups in this memory. Security information such as the cal factor frequency needs to be removed from the power meter if the power meter is moved out of the secure facility. This can be accomplished very easily by using the Secure Mode on the Power Meters. This function enables the user to completely wipe the non-volatile static RAM of all information. How the Secure Mode Works: The user sets the secure mode on the power meter. When the power meter is next turned on, the non-volatile static RAM is completely purged of all information. The power meter then sets the factory defaults for the current settings. Clearing the Non-volatile Static RAM on the ML2400A/ML2430A Series: Press System /more /more /more and then Secure. Now press Secure again so that the top line of the display reads System SECURE state Clear memory. Now switch the power off and then on again. The power meter will now power up with the non-volatile static memory completely purged. The code execution variables are also purged at power on as well. The secure state can be set over the GPIB using the following command: SECURE ON Clearing the Non-volatile Static RAM on the ML2480/90A Series: Press the hard key System (LHS) and then Service (RHS) and then toggle Secure so that the green light is active. Now switch the power off and then on again. The power meter will now power up with the non-volatile memory completely purged. The code execution variables are also purged at power on as well. The secure state can be set over the GPIB using the following command: NVSECS ON For more information on the power meters, please see the relevant manuals or contact: powermeter.support@eu.anritsu.com

What is stored in the EEPROM on the MA24xxX power sensors, and what type of EEPROM is it?

Anritsu manufactures several different families of sensors. All families have an EEPROM type of memory device in the power sensor. All A,B,C sensors (except MA2490/1 series,MA2411 series) contain a 64Kbit, 8K x 8 EEPROM All D sensors, MA2490/1, and MA2411 series sensors contain a 128Kbit,16K x 8 EEPROM EEPROM Contents: The EEPROM is used to store the following information: . Linearity data . Temperature Correction Coefficients . Sensor ID . Factory cal factor data . User cal factor table data Only the user cal factor table data can be erased without the functionality of the sensor being affected.

Where can I find information on how to erase my product's memory?

Please contact your Sales Representative or Technical Support at 1-800-ANRITSU (1-800-267-4878) for memory erasure /letter of volatility information.
