BitScope DSO 2.2 connected to the SYDNEY BitScope (click to enlarge)

If you run the standard BitScope DSO on your PC when connected to the Internet it will connect to a BS300N in our Sydney R&D center which we have put on the Internet.

Connect to the SYDNEY BitScope from
anywhere in the world via the Internet.

The screenshot above shows BitScope DSO Version 2.2 when connected to SYDNEY.

It's easy to try this on your own PC:

1. Download the BitScope DSO.
2. Unpack the zip (or tgz) archive.
3. Open the dso folder and run the DSO installer (or run "as is" in Linux).
4. Click the POWER button and wait a few seconds for the DSO to connect.

Assuming all goes well, you should be connected to the SYDNEY BitScope and see a DSO screen that looks like the one pictured at the top of this page.

The status bar at the bottom of the software should report:

• DSO version string (eg, DSO 2.2 9B17A).
• BitScope firmware revision (eg, BC000301).
• SYDNEY BitScope identifier (RE52HO10).
• Connection address (either SYDNEY or sydney.bitscope.net).
• Connection speed and status (eg, 5.5kB/s & CONNECTED).

If you see all of the above then congratulations, you are now connected to a live BitScope and you can try out all the features of the DSO !

The magic of this remote connection is made possible by BitScope Networking.

The waveforms you see on your screen at SYDNEY are generated by a WavePOD.

Using BitScope DSO Online

To recapture and update the display click the TRACE button.

To see a repeating trace click the REPEAT button.

The repeating trace will terminate automatically after about 20 capture frames. Click REPEAT again to see another 20 frames. (Note: the screen fresh rate on SYDNEY is about 20 times slower than if you're connected to a BitScope locally).

The trigger is configured to fire on the falling edge of channel A as it crosses zero.

You can adjust the trigger level, change to channel B (which has a positive going square wave) or try out any other DSO control.

Take a look at the online DSO Online Guide for more operational details.

So you're having some problems?

When running the DSO on SYDNEY you need to be aware that:

1. The Internet can be slow depending on the speed of your connection and where you are. Normally you should see a screen update within a second or so (in ALT or CHOP mode).

   By way of comparison, it typically takes about 50 mS to capture and upload a frame with BS300N when connected locally. The animation above should give you the idea.

   The newer models are even faster.

2. Normally one DSO connects with a BitScope at one time.

   However, more than one person may connect to SYDNEY simultaneously.

   This means that while you're looking the data it may unexpectedly change (when someone else clicks the TRACE button using different timebase or other parameters).

   If this happens, just click TRACE to refresh your display.

   If the waveform continues to be wrong, it may be that SYDNEY has been reconfigured to a different mode by another visitor. In this case reselect the Instrument (eg, SCOPE, CHOP etc). This will reconfigure SYDNEY to work with your DSO again.

   If the problem persists, perhaps you should have a coffee while the other person finishes up what they're doing :-)

3. You may not be able to connect if your PC is behind a firewall.

   Network BitScopes use the UDP ports 0x4000 and 0x4001 (by default).

   If your ISP or network adminstrator blocks UDP protocol ports, or these specific ports are blocked, you will not be able to connect.

4. The DSO is preconfigured to talk to the SYDNEY BitScope.

   However, if you have installed an older version of the DSO, this may not still be the case.

   To check, click the SETUP button and ensure the SYDNEY entry appears first.

5. If you're still having trouble talking to SYDNEY live, perhaps you'd like to try replaying some data recordings made with Sydney using the DSO Data Recorder's Offline Replay.

We've put the SYDNEY BitScope online for your enjoyment and investigation, and to demonstrate the sort of things that are possible with BitScope Networking.

An important benefit of the BitScope solution is that unlike some other systems, there is no PC at the SYDNEY end of the connection, just a BS300N directly connected to the Internet via a LAN !
