Unit Ut60e Software: Benefits and Advantages of Using a RS232 or USB Cable



There is also a C++ based software out there which can read andinterpret the data from the digital multimeter. The older version iscalled dmm_ut61e and the newer version ut61e-linux-sw, both ofwhich you can find in my repositoryut61e_cpp on Github.




Unit Ut60e Software




The PCBs arrived a few days ago and I assembled one unit for testing. A few parts are missing because they are on order and should arrive soon. Here are a few pics until I prepare the documentation:


This is not it. This is the basic circuit that will be used as a starting point: a voltage divider with a non-inverting unity gain amplifier as an input buffer. It works as a universal 0-5V analog input and can be easily expanded to 0-10V using a different value for resistor R2 (see notes below). Another advantage of R2 is that it provides a known reference when nothing is connected to the input so you can also detect broken wire conditions for resistive sensors. Read the rest of this entry


Product Features *UT58 series have large screen, full-functional symbol display, input connect reminder and overload protection in whole range. *UT60 has data hold, duty cycle, MAX/MIN keep, backlight UT60A-CN none,full-symbol display , auto power off and overload protection in whole range. It is matched with RS232 test software, UT60E series can easy transmit measuring data to PC for analysis.Product Display UT58series

The design is simple enough, we are sure you could easily hack the unit to do different things. Most coverage stops at 30MHz, but there is an FM band, so we wondered if you could get the thing to work on other frequencies, too.


I am very wary of SDR and software radio in general. Seeing that generating a sine wave vs. a square wave mess of harmonics that gets you into an FCC mess if transmitting, the local oscillator of a receiver has to be just as pure.


I agree with the concerns regarding lack of RF filtering in the Chinese radios. There needs to be at least some bandpass filtering ahead of the on-die LNA. I have been looking at adding the auto-switched receive bandpass filter bank used in the SoftRock Ensemble RX III direct down converting software defined radio (DCSDR) design. The schematic for the SoftRock Ensemble RX III is shown in [1]. The SoftRock SDRs are sold by Tony Parks, KB9YIG on the FiveDashInc site [2], but I do not see the Ensemble RX III on the FiveDash site yet, maybe it is too new. 2ff7e9595c
