1 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.

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. To learn more, refer to Chapter 2, Basic Operation.
Digital Modulation
In this mode, an internal baseband generator in the transceiver modulates a
CW signal with an arbitrary I/Q waveform (ARB). The ARB waveforms are
downloaded through a remote interface into the ARB memory. The ARB
waveform setup is accessed using the RF Source tab, followed by the
Modulation Setup key. To learn more, refer to Chapter 4, Basic Digital
Operation.

Table 2-1 Online Help Access
Press the question mark key for comprehensive help information. The online help is
context-sensitive (that is, the question mark key opens to a page that is relevant to
the last key you pressed). Also, while the help screen is open, press any key, and a
page relevant to that key is displayed; the normal key function does not execute.
Press ESC to exit the online help.
Setting RF Source parameters
The source functionality is accessed by selecting Input/Output key as below.
Selecting the Input/Output key opens up a softkeys menu under the RF Source
tab on the right side of the application window. These keys allow complete
configuration of the corresponding tab’s parameters.

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).
1. Select the Input/Output key.
2. Press the RF Source Tab (viewed on right of softkey menu).
3. Press Source Preset softkey.
Source User’s Guide 11
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. Choose a register in which to save the state by pressing one of the
Register keys. (A register with no state saved in it is in blank; when you
save a state in it, the register is labeled with the date and time.)
3. Alternatively, you can save the state to a file rather than to a register. Click
the Save To File key in the upper-right corner of the window, and use the
file-save window to chose a name and location for the file.
4. Recall a saved state by clicking Recall key, followed by the State key.
5. Choose a register from which to retrieve a state by Selecting one of the
Register keys.
6. Alternatively, you can retrieve the state from a file rather than from a
register. Click the Recall From File key, and chose a name and location for
the file.
Selecting Source Output
To select the output port for the source, access the Input/Output menu.
7. Click Input/Output, RF Source tab, RF Output Port, RF Output.
8. Select from RF Output, and RFIO HD. If you select RF Output, this means
that the RF Output designated as an output will be used.
