The TiePie equipment range is proudly represented in NZ by AECS Equipment.
The HP 3 series digital oscilloscopes are available in 3 different models,
The HP3-5 has a maximum sample rate of 5 MS/sec in oscilloscope mode and it has a Maximum sample speed in streaming mode (transient recording) of 500 kS/sec
The HP3-20 has a maximum sample rate of 20 MS/sec in oscilloscope mode and it has a Maximum sample speed in streaming mode (transient recording) of 2 MS/sec
The HP3-100 has a maximum sample rate of 100 MS/sec in oscilloscope mode and it has a Maximum sample speed in streaming mode (transient recording) of 10 MS/sec
What does 100 MS/sec mean?
100 MS/sec means 100 million samples per second. Which means in laymans terms that the scope's input checks what the voltage level is 100 million times per second. These measurements will be plotted on a computer screen and joined with lines (interpolation). As with any measurements, the more samples you take the more precise the result.
All three models, the HP3-5, HP3-20 and the HP3-100 hava a recording buffer of 1MiSamples
What is a recording buffer?
A recording buffer is the amount of measurements which can be held in the scope's own memory before it sends it via the USB cable to the computer or laptop in block mode. The HP3 series scopes can hold 1.2 million measurement points in its memory / processor. Not one detail of a signal needs to be missed anymore! The large recording buffer makes it an ideal scope for finding for example intermittend faults.
The direct voltage input of the HP3 series is 800 Volts
The HP3 series scopes have a very special feature, in that its direct differential input is 800 Volts. The 10 bit direct input converter of 800 Volts means that no attenuators need to be used. It makes the scope ideal for measurements on for example Automotive Hybrid High voltage systems. The cables and tool are CAT III rated.
Most scopes have a 20V max direct input or some even a 50V max direct input, which makes them inmediately unable to measure most automotive signals, as an attenuator has to be used for higher voltages. Attenuators will distort high speed signals.

What is the difference between oscilloscope and Transient recorder?
The HP3 can be set up as an oscilloscope, which means it will measure at high speed, collect the data in its on board recording buffer, once the buffer is full it will send the data to the PC. This will allow the highest possible measurement speeds, but the measurement "blocks" will have small gaps in between. There for a large buffer is best, to span as wide as possible.
The HP3 can also be set up as a transient recorder, the transient recorder will stream data to the PC continuously. The data transfer rate and therefor the measurement speed is limited by the communication speed between the scope and PC and the PC internal data processing speed. A slower measurement speed means a less precise signal. The Streaming speed of the HP3 is never the less still higher than most common oscilloscopes!
Multiple scopes in Multichannel software, what is the point?
It is possible to connect the HP3 to a laptop/PC together with one of the following instruments:

It should be noted that the HP3 does not work in conjunction with the ATIS software, so it requires an experienced and trained scope user to set-up the tool and to recognise the patterns to be good or faulty.
