Using the Digitizer cards for RADAR measurements
The Multiple Recording firmware option allows a high-speed series of waveforms to be recorded with extremely fast repatition rates. Also see the "UF2 Multiple Recording option" training below.

| |
Using the AWG cards for generating RADAR signals
The Multiple Replay option allows a very fast series of waveforms to be generated, each on a trigger event. See also the "UF2 Multiple Recording option" training below.

Sample Rate Determination
This application note describes how the sampling clock operates on the PCI (UF series), PXI (UX series and CompactPCI (UC series) of cards. Shows how to calculate the actual resolution achieved by the clock to your requested sample rate. Not applicable to the new PCI (UF2 series) cards.

Dynamic Specification Measurements
How do we obtain the dynamic specifications listed in the datasheets? This application note describes the measurements in detail so that you can re-produce them with your own UltraFast card to see the validity of our specs.

Output/Input Delays for UF/UC/UX.7000 Digital I/O cards
If using one or more of the UF7000, UC7000, UX7000 cards for both digital pattern generation and recording of a device under test, it is helpful to know the output/input delays.

Comparison of UF series and new UF2 series of PCI cards
While the UF series are still available to existing customers, for many the best choice for future projects will be the new UF2 series. Both are compared side by side in this application note.

Advantages of simultaneous sampling over multiplexed
Why is it an advantage to use an ADC per channel? What's time skew between channels?
[flash..]

How the Dynamic Parameters are measured
Confused about SNR, THD, SFDR, ENOB? This presentation explains what these mean and will help you choose the right card.

Multiple card synchronization for the UF2 series
Describes the Star Hub option that allows 2 up to 271 cards to be synchronized by clock and trigger.
[flash..] |
| |
Describes the various trigger modes
One of the main advantages to the UltraFast cards is their range of trigger options
[flash..]
|
| |
Channel selection options for the UF2 series
What possibilities exist to select active channels for the Digitizer and AWG cards
[flash..] |
| |
UF2 memory: Standard mode and FIFO mode
Presentation describes these modes for Digitizers, but also applicable to AWG and Digital cards.
[flash..] |
| |
UF2 Multiple Recording option
Presentation describes Multiple Recording for Digitizers, but also applicable to AWG and Digital cards. See also the description with respect to RADAR signals above.
[flash..] |
| |
UF2 Gated Sampling option
Presentation describes Gated Sampling for Digitizers, but also applicable to AWG and Digital cards.
[flash..]
|
| |
UF2 ABA option
The ABA mode allows the digitizer/digital cards to operate as both a datalogger and transient recorder. Slow to high-speed sampling on a trigger event.
[flash..]
|
| |
UF2 Time Stamp option
Allows you to record exactly when those trigger events occurred.
[flash..]
|
| |
UF2 Base IO option
Does more than just adds 8 slow Digital I/O lines to the cards. You can use these as additional trigger inputs, feed in a reference clock and gate TTL triggers.
