How the GaGe Digitizer was used: The GaGe Digitizer was used in conjunction with a dual-
channel spectrum analyzer (SA) based on spatial-spectral (S2) materials. This setup monitored
the outputs of a dual-drive, dual-port optical Mach-Zehnder interferometer, which received
inputs mimicking signals from a two-element antenna array. The digitizer helped in capturing
and processing the signal data in real-time with high precision, allowing for sub-millisecond
updates and sub-megahertz resolution.

How the GaGe Digitizer was used: The GPS receiver employs a GaGe digitizer to sample
intermediate frequency (IF) GPS signals at a predetermined rate. These sampled signals are
stored in memory for subsequent processing. The receiver’s digital signal processor (DSP)
executes fast convolution operations on the stored signals to derive pseudo range information,
enhancing processing efficiency.

measure the time of flight of light pulses after they bounce off a diffuse reflector, aiding in the
reconstruction of the hidden object’s 3D structure.

How the GaGe Digitizer was used: The GaGe Octopus CompuScope PCI bus was employed
to digitize and record signals from the TlBr detectors. The data acquisition involved capturing
voltage signals from both anode pixels and the cathode, which were then analyzed using
custom Matlab code to ensure accurate gamma-ray detection and resolution.

How the GaGe Digitizer was used: The iNIRS system employs a Mach-Zehnder
interferometer with a frequency-swept narrow linewidth laser to measure spectral interference
fringe patterns. Fourier analysis of the detected signal enables TOF-resolved intensity
determination, crucial for quantifying optical properties and dynamics simultaneously.

How the GaGe Digitizer was used: The GaGe Digitizer, with its high sampling rate of up to 40
M samples/s and 8-bit resolution, was used to capture high-frequency electromagnetic (EM)

How the GaGe Digitizer was used: In Phase IV testing, the GaGe digitizer was integral to
the PulseEcho system. It was triggered by an Agilent waveform generator to eliminate previous
jitter issues. The digitizer converted ultrasonic signals from the transducers into digital data for
real-time analysis, allowing the system to detect and measure the settled particles in the slurry
accurately.

How the GaGe Digitizer was used: The GaGe digitizer played a crucial role in verifying the
functionality of the PZT-PVDF stacked transducer through pulse-echo experiments. It captured
the echo signals received by both the PZT and PVDF elements, allowing for precise
measurement and comparison of the signal delays. Additionally, the digitizer facilitated the
reception of broadband acoustic emissions during experiments involving microbubbles exposed
to ultrasound pulses.
