 Unique Advanced Features

  • The Hierarchical Protocol Tree View organizes the captured USB protocol data into a a format that exactly reflects the nesting of the actual USB protocol items on the bus. This greatly eases understanding of the USB protocol. Most other USB Protocol Analyzers use a primitive block-type display which makes it very hard to see the overall hierarchy of the complex data being communicated.
  • Multiple time-correlated views of the data are simultaneously available, allowing you to easily see transaction, packet and bus-level details from the highest to lowest abstraction levels at a glance. Some other USB Protocol Analyzers require you to change the protocol view to view the data at a different abstraction level, resulting in loss of situational awareness of your location within the overall trace.
  • The 1480A Decodes and displays all bus events down to the most detailed differential D-/D+ bus state changes with 16.67 ns resolution. Other USB Protocol Analyzers only show you the higher-level Protocol View without possibility to get to the lowest-level bus states.
  • A very small physical format and a bus-powered design allows easy transportation and convenient use with laptops (only 4.90” x 4.10” x 1.4” / 8.8oz or 125 x 105 x 35 mm / 250g).

1480A USB Protocol Analyzer Software Tutorial

Description

The Model 1480A USB 2.0 Protocol Analyzer with OTG decoding is specifically designed for the road-warrior. It will easily slip into your coat pocket or laptop bag for those trips where bringing a large USB analyzer is not convenient. The physical format is very small, only slightly larger than a pen or a computer mouse. The enclosure is made out of very high-quality brushed aluminum.

The data captured is in real-time transferred to the Analysis PC where it is analyzed and displayed by the PC Software. The USB Analyzer has no limitation of the data size captured as data is streamed in real-time directly from the link under test into the PC application's tree view display. This allows you to capture many hundreds of MB of data (only limited to the size of RAM in your analysis PC).

The 1480A contains a 32MB FIFO buffer SDRAM that smooths out bursty traffic such that temporarily bursty traffic on the link under test will not cause the USB Analyzer-to-Analysis PC link to be saturated. The sustained maximum capture speed to the analysis PC largely depends on the speed of the capture PC. As a rule of thumb, as long as the throughput on the link under test is under 15 MB / s then the analysis PC will keep up with the captured data speed without the buffer FIFO filling up. Note that the 1480A USB Analyzer will never lose captured data (regardless if the link under test is saturated) since the captured data is always buffered in the SDRAM FIFO before being sent to the analysis PC.

The 1480A USB Protocol Analyzer is FPGA-based which makes it fully programmable with each new software upgrade. This allows us to fully remotely deploy logic and software upgrades, if needed. This means that you will never need to send your hardware to us for upgrade as more advanced software like class decoders are purchased.

The PC Analysis Software displays data as it is received from the USB Analyzer hardware so you will not have to wait for lengthy data decoding before you can start analyzing the captured data. As USB Transactions and Packets are captured, they will be decoded and added to the tree view in the PC Analysis software. This makes it very easy to understand the sequence of events in the captured data. Detail views display the details for selected Transactions and Packets in the tree view as they are clicked on. The PC Analysis software also decodes payload data in hex format and displays it in the hex view pane.

Technical Specifications

1480A LS/FS/HS USB Protocol Analyzer Technical Specifications.
Dimensions / Weight 4.90” x 4.10” x  1.4” / 8.8oz (125 x 105 x 35 mm / 250g)
Analysis PC Requirements 32-bit (x86) and 64-bit (x64) Windows versions (XP SP2 or newer). Pentium 4 or faster CPU is recommended.
Supported USB Standards USB 1.0, USB 1.1, USB 2.0, OTG 1.3.
Supported USB Speeds The 1480A automatically detects device connection in high speed (480 Mbps), full speed (12 Mbps), and low speed (1.5 Mbps).

Note: HS Devices are initially connected as FS devices. Only after successfully having completed the Device and Host Chirp Sequences do HS-capable devices enter HS mode. The 1480A fully supports automatic detection of both Device and Host Chirp.
Maximum recorded data length Unlimited. Only the available disk and memory of the Analysis PC limits how much data can be captured and analyzed.
Built in FIFO buffer 32 MB. The FIFO buffer is used to smooth out the data stream captured from the Link Under Test. Note that the FIFO buffer will fill up if the Analysis PC is unable to read out data fast enough from the 1480A. In this case, the recording will automatically stop and the PC application will display the captured data up until the point where the FIFO filled up.
Analysis PC Interface USB 2.0 Type "B" Connector
Link Under Test Interface USB 2.0 Type "A" and "B" Connectors.
LED Indicators
  • Host Power: Indicates when the 1480A unit is powered and the Analysis PC Device Drivers have been installed.
  • Link Power: Indicates that the Link Under Test is powered by the Host.
  • Link Activity: Indicates when link activity is detected.
Captured bus events and packets

All bus activity down to the smallest detail is captured and stored into the .usb file when recording. The 1480A Software displays all the captured information from the lowest link level up to the highest protocol level. In addition the VBus voltage is continuously monitored and stored in the capture file.

For detailed information of the captured data, please see the datasheet for the NXP ISP1505A USB Transceiver.

Great for USB 1.1 and USB 2.0 Protocol Analysis, January 28, 2016
By B. Waggoner

This review is from: 1480A USB 2.0 Protocol Analyzer

Not perfect, but nearly so. Windows driver and software installation could be better documented. But once it is up and running, it is very powerful and very easy to use. The user interface (always a difficult software project) is great. I was capturing and analyzing and saving data within 5 minutes, and found a USB device protocol bug within 10 minutes. It is easy to drill down from the high level protocol view to the low level protocol details, if and as desired. Provides detailed timing information for each USB packet, and packet timing is the origin of many errors. Paid for itself already. Much less expensive than available alternatives. Small and very portable. Highly recommended.

This is a real life saver!  Shipping was prompt and it had already helped us pinpoint a problem our customers have told us about but we were unable to definitively pinpoint with a software only analyzer. The mysterious bug was identified within 2 hours of getting the analyzer in the morning and a patch for the problem was issued before lunch. Amazing!

Excellent delivery Us to UK
identified my problem within minutes of using the analyzer.
For the money excellent value, tells you all you need to know when debugging a USB device, can't see why you would need to  pay out for a more expensive product

If you really want to know USB, this product is an indispensable tool. It is very easy to use and the support is very good too. You can use it to analyze traffic between a 32 bit microcontroller with USB OTG and a device like a USB key, This type of tool at this price is AMAZING!

I think you have to give this product a rating of 5 simply from the value for money aspect. Previously I had been using hired or borrowed USB analysis devices which used the XL type block type of display so the ITI GUI took a little getting used to, but not so much. The grouped transaction display is actually much easier to deal with especially when combined with the details view and packet breakdown details found within the lower RH window. Somebody has put a lot of thought into this. ITI as a company are easy to deal with and quick to respond to questions etc.
