Select the appropriate link below to view the required release.
No new features or measurements have been added to this version of the firmware. The same hardware requirements apply as in the A.11 Release, see Support for EGPRS hardware .
This firmware release is compatible with EGPRS capable hardware. No new features have been added to this version of the firmware.
E1960A test application release A.10.xx and earlier are not compatible with E5515B or E5515C chassis with EGPRS capable hardware. Loading E1960A A.10.xx or earlier will make the mainframe inoperable and require Keysight service. The following applications are not compatible with EGPRS capable chassis: E1960A (release A.10.xx and earlier), E1964A, E1985A, E6701A and E6701B.
This firmware release provides the ability to run E1960A firmware on E5515B or E5515C chassis containing EGPRS capable hardware. Chassis containing EGPRS capable hardware include:
If you have previously been using any revision of the E1960A GSM test application on an E5515A, E5515B, or E5515C chassis then this revision will also run. The second RF source, Option 002, is required to run E1960A on E5515B and E5515C chassis.
This firmware release adds new frequency bands, half rate speech mode and a spectrum monitor.
This firmware release will run on an E5515C chassis with Option 002. If you have previously been using any revision of the E1960A GSM test application on an E5515A or E5515B chassis then this revision will also run.
For access to the spectrum monitor feature requires your chassis be one of the following:
This release provides you with the GSM450, GSM480, GSM750 and RGSM frequency bands.
Half rate speech channel mode has been added. For more details refer to Channel Mode Setup .
A Spectrum Monitor measurement feature has been added. This allows you to find, identify and measure transmitted signals from your mobile phone. It can also be used for spur measurements in the transmit band. For more details refer to Spectrum Monitor Description .
This firmware release adds new features to the Output RF Spectrum and Power versus Time measurements.
This firmware release will run on an E5515C chassis with Option 002. If you have previously been using any revision of the E1960A GSM test application on an E5515A or E5515B chassis then this revision will also run. However, if you wish to run this test application on an E5515A or E5515B chassis for the first time, contact your local sales representative.
The Phase and Frequency Error measurement has been enhanced to include a confidence level feature. Using confidence levels for your measurements can reduce your test time. Confidence levels simply end the measurement early, that is, before all the multi-measurements you specified are taken. It ends the measurement early only if it determines statistically that the rest of the measurements should pass. You can set the confidence level and the measurement limits. For more information on this feature refer to Confidence Levels .
This release gives you the first revision of GSM which can be used for the E1985A GSM_AMPS/136_GPRS fast switching test application. The previous GSM release (A.07) only allowed you to switch quickly between GSM and AMPS/136, whereas this GSM revision also allows you to also switch quickly between GPRS.
Internal graphical measurements for: Power versus Time, Output RF Spectrum, Phase and Frequency Error and I/Q Tuning.
For more details on these graphical measurements refer to one of the following step-by-step measurement procedures:
This release gives you the first revision of GSM which can be used for the E1985A GSM_AMPS/136 fast switching test application. To allow the GSM test application to operate in the fast switching environment with AMPS/136 two existing GSM commands had to be changed. These commands were:
If you previously used either of these commands you must change them to the new commands to allow your code to run.
|
SETup:IQTuning:REFerence[:MANual][:FREQuency]:CHARacter:GSM . This command allows you to use the same settings as with the previous command, that is NEG67KHZ, ZEROKHZ, POS67KHZ, and AUTO. You can use this command for the GSM I/Q Tuning measurement whether or not the GSM test application is the currently active format. |
|
|
Alternatively you can use the following commands which are consistent with the format of the commands and settings in AMPS/136: |
|
|
"CALL:MS:REPorted:REVision:CHARacter:GSM?" on page 236. This command returns the same values as with the previous command, that is, UNKNown, PHASe1, and PHASe2. You can use this command for the mobile's revision whether or not the GSM test application is the currently active format. |

Alternatively you can use the following commands which are consistent with the format of the command and setting in AMPS/136: |
Test Application selection for multi-format operation
Menus have been added to the System Configuration screen which allow you to select between different Test Applications that are installed in the test set. This feature can also be accessed remotely within the SYSTem subsystem using the command
SYSTem:APPLication:SELect[:NAME]
.
It is not recommended that you switch to a GSM Test Application that has a revision earlier than A.04. Earlier revisions did not have the capability to select Test Applications.
There may be up to a three second delay between the time the Test Application is selected and it being implemented in the test set.
Options installed display is now active
The Options Installed display on the System Configuration screen has been activated to allow for the optional second source. Although the second source has been optional since the A.03 release, the Options Installed display has remained blank until this current release.
Usability enhanced through gray fields
Non-enabled menu items are now denoted as gray text, versus enabled menu items that are a standard black text. Currently there are no GSM Test Application menu items that use this feature.
Measurement time-out resolution increased
The measurement time-out resolution has been increased from 1 second to 0.1 seconds. The minimum time-out has also been reduced from 1 second to 0.1 seconds.
Warning messages can be masked from the display
A new command is available in the DISPlay subsystem which allows you to set whether or not the test set displays and beeps warning messages. For further information on this command refer to
DISPlay:MESSage:MASKable:STATe
. This feature is also available over the manual interface (the Maskable Messages Display State field is available in the Instrument Setup menu in the System Configuration screen).
EFS
The Enhanced Full-rate Speech (EFS) feature provides the ability to set up a call in EFS mode.
SACCH Tx Level Signalling
The mobile can now be commanded to use a different Tx level by signalling using the SACCH header alone. In previous releases a FACCH assignment as well as the updated SACCH header was used.
I/Q Tuning
A new measurement that can be used to determine the quality of an I/Q modulator by measuring the power of spurious signals at harmonics of 67.7 kHz.
Simultaneous BER results
An enhancement to the BER measurement now allows all types of BER measurement results to be returned at the same time if required.
Dynamic Power
A new feature that performs a series of rapid power measurements on a mobile station. This is only available via the test set's remote user interface.
Remote clear of error messages on screen
A new command can be sent over the GPIB to clear error messages from the screen to enhance use of the test set in a remote situation. Previously, error messages on the screen could only be cleared through manual intervention, by pressing a key on the front panel. For further information on this command refer to
DISPlay:WINDow:ERRor:CLEar
.
Status field indication of external or internal reference
A status field has been implemented on the screen to indicate whether the test set has locked to an external or an internal reference.
Beeper ON/OFF setting is non-volatile
The ON/OFF setting of the beeper is now maintained through power-off. Previously, a power cycle would reset the beeper to its default state of OFF.
Enhanced status subsystem for multi-format capability
The status subsystem has been enhanced with radio system nodes where necessary for future multi-format capability. This will cause some status subsystem commands to be in error condition, unless they are replaced with the modified commands. The commands are:
Instrument configuration information available remotely
Information on the instrument hardware can be obtained through a remote command over the GPIB, and through a remote command via the LAN and a web browser. For further information on the commands refer to
Hardware Configuration Report
.
Enhanced instrument information on the Configuration Screen
The Instrument Information display on the Configuration Screen, now includes Subnet Mask and Gateway Default information in a new, improved information display.
*IDN? returns "Keysight Technologies" in the manufacturer's field where previously it returned "Hewlett-Packard".
RF Generator frequency range is now matched to the RF Receiver frequency range
Previously the RF Generator had a low end limit of 45 MHz, while the RF Receiver has always had a low end limit of 292.5 MHz. The RF Generator is now limited to 292.5 MHz to enhance testability and supportability of the test set.
