Do I need to pay when updating the software?

The update of the main program is for free, and customers can purchase the Protocol Analyzer module and other modules with special functions as their requirements.

Can I borrow the Logic Analyzer with a Protocol Analyzer for two weeks?

Zeroplus can lend you the trial machine and the trial Protocol Analyzer, but our company has a rule about that, the trial machine can be lent out for three days to seven days. If you feel that the functions of our Logic Analyzer are well, and it is suitable for your requirements, we recommend you to purchase one firstly.

What is the Trigger Condition?

The Trigger Condition represents a waveform status which needs to be found.
For Example: If users want to trigger the signal at the Rising Edge and analyze the waveform after the Rising Edge appears, they can set the Trigger Condition of the channel as the Rising Edge.

What is the synchronous State Mode?

Because the sampling clock and measured object can be directly related, and are controlled by the latter, signals of the former and the latter can proceed simultaneously. We call this “State Mode”. In this mode, the measured object provides the sampling clock. State Mode
is that the Logic Analyzer can obtain sampling data from the test equipment synchronously. In other words, when the test equipment has a signal or signal group, it is the time to get the signal. For example, while the test equipment is sending out one Rising Edge, the Logic Analyzer can start to obtain one signal.

What is the asynchronous Timing Mode?

Since the sampling clock and tested objects are not directly related to each other, and the
former won’t be controlled by the latter, the sampling clock and the tested signals will
not be done at the same time. We call this “Timing Mode”, which means that in the
same time interval (the sampling time is 1/Sampling Frequency), you can get sampling data from the test equipment at one time, for example, sampling the data from the test equipment every 5ns (the sampling frequency is 200MHz).

What is the Logic Analyzer?

The Logic Analyzer is a tool that sieves out and shows the digital signal from a test
equipment by using a clock pulse. The Logic Analyzer is like a digital oscilloscope.
However, it only shows two voltage states (the logic status 1 and 0), differing from many voltage levels of an oscilloscope. The Logic Analyzer has more channels than an
oscilloscope to analyze the waveform. Since the Logic Analyzer obtains only signals 1 and 0, its sampling frequency is slower than an oscilloscope, which needs many voltage ranks.
Moreover, the Logic Analyzer can receive many signals during a test.
