RIGOL DNA-TDA10 TIME-DOMAIN ANALYSIS SOFTWARE

Overview

The RIGOL DNA-TDA10 is an advanced Time-Domain Analysis (TDA) Measurement Application Option designed to expand the capabilities of the Rigol DNA800, DNA5000, DNA6000 and DNA6000-R Series Vector Network Analyzers. While a standard VNA measures characteristics in the frequency domain, the DNA-TDA10 software utilizes an Inverse Fast Fourier Transform (IFFT) to mathematically convert these parameters into the time domain.

This powerful transformation enables engineers to visualize the time-domain characteristics of a Device Under Test (DUT). By measuring the delay between a transmitted pulse and its reflection, and combining it with the signal's transmission rate, the TDA software makes it highly efficient to determine impedance distribution and locate exact faults—such as open circuits, short circuits, and minor impedance variations—along a transmission cable or fixture.

Product Features

Multiple Transform Types

Adapt the analysis to your specific measurement needs with three distinct transform algorithms:

• Band Pass: Features a wide pulse and low resolution. Ideal for rapidly locating problems in wideband scenarios and measuring band-limited devices.

• Low Pass Impulse: Utilizes a narrow pulse for high resolution, making it easy to identify tiny impedance variations in devices that pass low frequencies.

• Low Pass Step: Generates a step signal with a sensitive rising edge to clearly identify inductive and capacitive discontinuities in low-pass devices.

Advanced Time Gating

Time gating acts as a powerful filter for your frequency-domain signals. By converting raw data to the time domain, applying specific filtering conditions (Band Pass to keep data, or Notch to remove data), and transforming it back to the frequency domain, engineers can effectively isolate desired responses and remove unwanted reflections from adapters or fixtures.

Precise Distance Transfer

Easily convert time-domain measurements into exact physical lengths. By configuring the specific Velocity Factor of your transmission medium, the software automatically translates the X-axis time coordinates into distance (selectable in Meters, Feet, or Inches) from the test port to the destination point.

Adjustable Window Functions

Fine-tune your measurements using the Kaiser Beta and Impulse Width window parameters. Increase the Beta value for higher time resolution (ideal for detecting close-range impedance discontinuities), or decrease it for stronger sidelobe suppression (ideal for detecting weak reflections or long-distance faults).
