Synth1000x2 board generates two independent sine wave outputs, each switchable via software or external TTL inputs, through up to 8 frequency/phase/amplitude profiles.
Berkeley, CA, May 20, 2014. Ultraview Corporation, a maker of high
speed data acquisition and frequency synthesis boards since 1989,
announces a Dual DDS PCIe board with rapid profile switching for
demanding uses in communications, RADAR, medical imaging, spectroscopy,
RF/Microwave testing and other critical applications.
Based on two AD9914 DDS ICs driven by single 3.5GHz CRO synced to a
1ppm-accurate TCXO timebase, the Synth1000x2 can be set to produce two
independent sine wave outputs, the frequency, amplitude, optional sweep
rate and phase of which can either be changed manually using either a
LabVIEW™ or QT GUI, or alternatively can be dynamically switched in real
time (in under 50ns), allowing creating of complex modulated carriers,
or rapid waveform sequences. High speed dynamic switching among up to 8
separate profiles on each synthesizer, can either be controlled by
software or by 3 external TTL inputs.
In the simplest mode, a user can simply use the LabVIEW™ or QT GUI to
program a single frequency or two separate frequencies, one on each
channel. Or, he/she can preset up to 8 frequency/phase/amplitude
profiles, and then just press a button to select which profile each
synthesizer is to use - much like a car radio.
If fast frequency/amplitude/phase switching is desired, the external
TTL rapid profile control mode allows each synthesizer channel to be
independently switched externally in frequency and/or amplitude and/or
phase. Up to 8 complete profiles can be programmed in advance, using
either a C program or via user entry into fields in a simple GUI control
panel. Then, the frequency profiles can be dynamically selected via a
3-bit TTL vector which may be externally input via a small connector
block containing 6 SMA connectors, 3 for each channel. Of course fewer
profiles may be selected. For example, for simple frequency shift
keying (FSK) a single TTL input can be used to tell the Synth1000x2 to
rapidly switch between two frequencies on a single channel.
Alternatively, instead of up to 8 profiles on two separate channels,
16 switchable profiles can be achieved on a single channel by connecting
the two outputs to a simple resistive power combiner.
While the Synth1000x2 is rated to produce frequencies from 0.05 MHz
to 800 MHz, it can, with reduced performance and amplitude produce
signals from 10 KHz to 1000 MHz.
In addition to the two programmable sine-wave outputs contained in
all Synth1000x2 models, the Synth1000x2-SQR model can concurrently
output two sine waves and two 1V p-p AC-coupled square waves with 200ps
rise and fall times, for low-jitter control of external apparatus, such
as heterodyned RADAR pulse generators and samplers. The frequency
range of the sine wave outputs is 0.05MHz to 800MHz, while that of the
2v p-p square wave outputs is 5MHz to 800MHz.
All models include 64-bit Windows™ 7/8 driver packages, as well as
comprehensive C example programs, and LabVIEW™ and QT GUIs for Windows.
Additionally C example programs and a QT GUI-based control panel are
included for CentOS 6.4 linux.
Figure 1 shows the Synth1000x2 board. Figure 2 illustrates the
LabVIEW™ control panel with 8 separate profiles set for each channel,
and the resulting complex output waveforms on the two channels when
externally switched via their TTL profile select inputs.
