The Model 2910 RF Vector Signal Generator is the first in a series of Keithley RF instruments that
sets a new price/performance standard. It’s priced significantly less than instruments or systems with
comparable levels of functions and performance and offers far more functionality and better performance than comparably priced equipment. While the Model 2910 offers capabilities and ranges that
make it ideal for production testing of today’s sophisticated mobile handsets, it also has features that
make it useful for applications like testing mobile communications infrastructure, RFICs, and wireless connectivity devices. The Model 2910’s exceptional testing capabilities and ease of use make it a
good choice for use in mobile communications research and education settings.
When characterizing or verifying DUT performance, the speed of the RF signal generator can have
a major impact on overall test throughput and, therefore, the cost of test. Higher speed also makes
it possible for manufacturers to respond quickly to increased volume demands. The Model 2910 is
designed to execute key tasks like frequency tuning, amplitude switching, and waveform changes
significantly faster than other products available.
The Model 2910’s continuous frequency range of 400MHz to 2.5GHz spans key mobile wireless
bands. Digital waveforms for key tests in major cellular formats (GSM, GPRS, EDGE, WCDMA, cdmaOne, cdma2000) for testing handsets are built in, as is support for analog modulation (continuous
wave, two-tone continuous wave, amplitude modulation, frequency modulation, phase modulation,
pulse modulation, and noise). The 64 megasample Arbitrary Waveform Generator (ARB)
and 40MHz modulation bandwidth support
downloading a wide range of externally generated signal waveforms. A 2MHz noise bandwidth
supports “quick-check” noise immunity tests on
a variety of devices.
The instrument’s software-defined radio architecture gives telecom manufacturers the testing
flexibility needed to keep pace with changing
wireless technologies, as well as fast frequency
tuning, amplitude settling, and waveform switching. New signal structures and instrument features can be incorporated easily and economically with ongoing firmware updates.

Higher Speed for Lower Cost of Test
A state-of-the-art digital signal processor (DSP) and high speed RF architecture provide the Model
2910’s speed and help reduce RF device manufacturers’ cost of test:
• Faster tuning. The Model 2910 can switch frequencies in less than 1.6 milliseconds for unmodu-
lated signals and less than 1.8 milliseconds for modulated signals, which is significantly faster than
many higher-priced competitive instruments.
• Faster amplitude settling. When changing signal amplitude levels, the Model 2910’s unique RF
output structure settles to specified level accuracy in less than 1.6 milliseconds for unmodulated
signals and less than 1.8 milliseconds for modulated signals, which is significantly faster than most
competitive instruments.
• Highly responsive controls. The Model 2910’s high speed response to user inputs from the front
panel or to programmed commands ensure fast waveform downloads and fast switching from one
waveform to another, eliminating waiting times.
• Large Arbitrary Waveform Generator. A built-in Arbitrary Waveform Generator (AWG) with
256MB (64 mega-samples) of waveform memory allows users to have many waveforms resident in
memory simultaneously. The large memory supports downloading ARB files created with external
software packages like MATLAB
Switch quickly between waveforms—typically in less than three milliseconds.
Powerful Built-in Tools and Capabilities
The most important digital signal structures needed to produce forward link (downlink) signals for
all the major cellular formats (GSM, GPRS, EDGE, WCDMA, cdmaOne, cdma2000) are already built in
to the Model 2910. The intuitive graphical user interface (GUI) greatly simplifies generation of nonstandard signals or modification of existing waveforms for GSM, GPRS, EDGE, WCDMA, cdmaOne,
and cdma2000 forward link (downlink) signals. The large arbitrary waveform generator memory
and 40MHz of modulation bandwidth extend the signal generation capability to virtually any signal
with up to 40MHz of bandwidth. For applications that require even more modulation bandwidth,
the Model 2910 gives users the external I/Q modulation inputs (with ≥200MHz of modulation
bandwidth).
The Model 2910’s continuous tuning capability from 400MHz–2.5GHz covers all the key mobile communications bands, but also expands its applications far beyond the production test floor. The userfriendly GUI, easy-to-use front panel controls, and range of analog modulation capabilities make it an
equally good choice for R&D applications.
Superior Signal Generation Accuracy
Digital baseband processing and optimal real-time digital reconstruction filtering allow the Model
2910 to deliver an extremely clean signal to a high performance I/Q modulator. As a result, the
modulator produces signals with outstanding
modulation quality. For example, the error
vector magnitude (EVM) for EDGE signals is
extremely low (<0.5%). This ensures precise,
repeatable signals that help minimize measurement errors.
Outstanding amplitude accuracy (<0.5dB, typically <0.3dB) and linearity (<0.05dB) minimize
signal level uncertainty, which minimizes measurement errors, simplifies the testing process,
and allows for tighter specifications for devices
under test.
