Keysight M9410A/M9411A/M9415A VXT PXI Vector Transceiver Source User’s Guide Source Overview The source in this instrument can be operated independently of the transceiver to provide arbitrary waveform generation to test wireless mobile devices. The source can also be used together with the transceiver to simultaneously test both the transmitter and receiver of a wireless device.
— with Signal Studio Software, the transceiver can generate 802.11 WLAN, W–CDMA, cdma2000, 1xEV–DO, GSM, EDGE, and more. For more details on hardware, firmware, software, and documentation features and options, refer to the data sheet shipped with the transceiver and available from the Keysight Technologies website at: http://www.Keysight.com/find/m9410a http://www.Keysight.com/find/m9411a http://www.Keysight.com/find/m9415a...
Source Overview Modes of Operation Modes of Operation The instrument source provides two basic modes of operation: continuous wave (CW) and digital modulation mode. Continuous Wave In this mode, the transceiver produces a CW signal. The transceiver is set to a single frequency and power level, which is set up using the RF Source tab menu.

Basic Operation Presetting the Source Presetting the Source Presetting the source is a method of restoring all source settings to its default values, after some or all of them have been changed. If you want to be able to return the source settings to the values they had before the preset, save the current state before you preset the source (see “Saving and Recalling States below).
Basic Operation Saving and Recalling States Saving and Recalling States The current state (including both source and analyzer settings) can be saved and later recalled. 1. Click file icon in the bottom bar, and click Save key to access the file operation window. Select State in the left side of this window. 2.
Basic Operation Setting Frequency and Power (Amplitude) Setting Frequency and Power (Amplitude) The M9410A/M9411A transceiver does not have an Automatic Level Control feature; amplitude accuracy is regulated by means of calibration for frequency and temperature variations. To set the frequency and power of the source output proceed as follows: 1.
Basic Operation Working with Files Working with Files — “Viewing a List of Stored Files” on page 18 — “Loading (Recalling) a Stored File” on page 19 The transceiver recognizes several types of files, such as state files, license files, and correction files. Files are stored in the controller internal storage. This section provides an overview of how to navigate the file menus, and how to view, store, load, and move files.
Basic Operation Working with Files Storing a File To store a file that you have set up, use the Save key as described in “Storing, Loading, and Playing a Waveform Segment” on page To store a transceiver state that you have set up and may want to re-use, use the Save key and select State from the sub-menu and select a register in which to store the state.

Optimizing Performance Using an Output Offset and Reference Setting an Output Reference Using an output reference, the source can output a frequency or amplitude that is offset (positive or negative) by the entered value from a chosen reference value. RF Output = reference value + entered value To set a reference: 1.
Optimizing Performance Using Amplitude Corrections Using Amplitude Corrections Amplitude corrections can be applied to both source and analyzer ports on the transceiver. The Amplitude Corrections arrays can be entered by the user, sent over SCPI or loaded from a file. They allow a user to correct the response of the transceiver for variations in signal paths external to the transceiver.
Optimizing Performance Using Amplitude Corrections Setting up a corrections table To set up the corrections table using the front panel, from the Corrections tab, select Ed it Correction. Click Insert Row Below to start the editing. The Frequency and Amplitude keys allow you to enter a frequency and the correction in dB that you require at that frequency.

— A segment is a waveform file that you download to the transceiver. — A sequence is a file you create in the transceiver source that contains pointers to one or more waveform files. The current M9410A/M9411A software only supports waveform segment operation and the waveform sequence operation will be supported in future.
Basic Digital Operation Storing, Loading, and Playing a Waveform Segment Storing, Loading, and Playing a Waveform Segment Before using this information, you should be familiar with the source file menus. If you are not, refer to “Working with Files” on page 18 and familiarize yourself with that information.
Basic Digital Operation Storing, Loading, and Playing a Waveform Segment Deleting a Waveform Segment on Internal Disk Use the following steps to delete a file on the hard disk. 1. Click file icon in the bottom bar, and click Recall key to access the recall sub-menu.
Basic Digital Operation Saving a Waveform Settings & Parameters Saving a Waveform Settings & Parameters This section describes how to edit and save a file header. When you download only a waveform file (I/Q data, which the source treats as a waveform segment), the source automatically generates a file header and a marker file with the same name as the waveform file.

Basic Digital Operation Saving a Waveform Settings & Parameters c.Save the current settings to the file header: Press the Save Header key. The settings from the white text column now appear in the gray text column. This saves the new current transceiver settings to the file header.
Basic Digital Operation Using Waveform Markers Using Waveform Markers The source provides four waveform markers to mark specific points on a waveform segment. When the source encounters an enabled marker, an auxiliary signal is routed to a rear panel trigger output. The marker that is routed to the TRIGGER 2 connector is selected using the Input/Output menu.
Basic Digital Operation Using Waveform Markers Marker Signal Response The source aligns the marker signals with the I and Q signals at the baseband generator. However some settings such as amplitude, filters, and so forth within the RF output path can create delays between the marker TRIGGER 2 output signal and the modulated RF output.
Basic Digital Operation Using Waveform Markers This example uses a sine waveform segment in the dual ARB Player. Factory–supplied segments have a marker point on the first sample point for all four markers. 1. follow the procedure on page 29 to select and load the waveform segment file you need.
Basic Digital Operation Using Waveform Markers Marker Polarity = Positive When marker polarity is positive (the default Signal Signal setting), the RF output is blanked during the off marker points. Marker Segment Marker Polarity = Negative When marker polarity is negative, the RF Signal Signal RF output is blanked during the on marker...
Basic Digital Operation Using Waveform Markers Pulse/RF Blanking always occurs on the low part of the signal regardless of the polarity setting. Using the TRIGGER 2 Signal as a Transceiver Trigger One of the uses for the TRIGGER 2 signal (marker signal) is to trigger a measurement instrument.
Basic Digital Operation Triggering a Waveform Triggering a Waveform Triggers control data transmission by controlling when the transceiver transmits the modulating signal. You can configure trigger settings so that data transmission occurs once (Single mode), or continuously (Continuous mode). A trigger signal contains both positive and negative states; you can use either for triggering.
Basic Digital Operation Triggering a Waveform Trigger Source Trigger Source is selected by pressing the Input/Output key, followed by the Modulation Setup, ARB Setup, Basic Control, Trigger Source keys. — Key - the waveform is triggered when the Single key is pressed —...
Basic Digital Operation Source Alignment Source Alignment Use the Alignments menu to provide a manual signal alignment of the source. When you execute an alignment of the source. The transceiver stops any sequence of the source, presets the source, and performs the alignment. Run the source alignment by pressing the System front-panel key, followed by Alignments, Align Now, Align Source.
Basic Digital Operation Licensing Licensing You can create your own signal waveforms to output from the transceiver ARB using a number of methods. One of them is to use Keysight Signal Studio which is a suite of PC-based signal creation software that allows you to create customized signals for multiple radio standards.
Basic Digital Operation Licensing Signal Studio waveforms can be downloaded to the instrument and placed into a waveform slot for a 48 hour trial period. This allows you to edit and reuse this slot for 48 hours. After the 48 hour time period the STATUS of this slot will be changed to LOCK REQUIRED.
