This thread caught my eye. Do you care to do a review on the Hantek scope? In particular, can this scope be controlled via the USB port?
One thing that I like about the Instek is that it has a documented programming interface, and you can interface
it to your own software (such as NI Labview, or Python/VISA). Does the Tekway have a similar interface?
How does the triggering, display, etc. compare? How is the brightness/crispness/viewing angle?
Oki, small Hantek DSO5202B/DSO5102B/DSO5062B - Tekway DST1062B/DST1102B/DST1202B review.Display :
The DSO is using InnoLux 7" TFT (AT070TN83 V1) with LED backlight,
It is a good display wth high contrast/brightness and do have anti glare.
Viewing angle is 6 o'clock, no differences to 3 o'clock and 9 o'clock. Only in 12 o'clock isn't that good (see display datasheet for more information)
The DSO is using native resolution (800x480), no double/quad pixeling tricks like with UNI-T CEL series.
A very good thing is the DPO-like display persitency, from 0.2s to infinite (Instek Accumulate is like infinite persistency on Hantek/Tekway, so no compare)
There is additionaly TFT refresh rate selectable between 30, 40, 50 aud automatic (which is i think 20 or less) frames/sec.
You can "see and feel" the refresh speed and the waveform changes.Menu:
Menu on the right side can be switched on/off (in single window mode), it is always on in double window mode.
Menu-speed is fast, a little-bit slower in long memory mode but still ok (this is new in current firmware version, it was amazing slow in fw 2.05.x)Trigger:
All standard triggers available :
Pulse (Pos/Neg, "<" ">" "=" "!=", 20ns to 10s pulse width)
Video (All/Odd/Even/LineNumber/AllLines - PAL/SECAM/NTSC)
Slope ("<" ">" "=" "!=", Time and V/sec scale)
Over Time (Pos/Neg, 20ns to 10s)
Alternate (Edge, Pulse, Over Time, Video trigegr per chan available)
Of course all triggers have additialy LF reject, HF reject, Noise reject, AC or DC coupling options
and Ext, Ext/5, AC50
Autoset have additionaly multicycle / singlecycle rising/falling edge waveformtriggers.Memory :
Sample memory can be switched between 4k, 40k, 512k or 1M (in real time sampling mode) up to 200µs time base (2ms record time)
It will change automatically to 512k in 200µs and higer time base if you in run mode.
In eq. sampling mode you can't change sample memory, however it seems to be using the real time sampling mode values.
Currently there is funny firmware bug (fw 2.06.2), with some specific combination of run&stop/single/time base change/memory length
the DSO is showing wrong data. This means don't use single shot with long memory (everything over 40k) in higher time base than 200µs.
Run/Stop is displaying proper data, single shot too as long you don't change time base. I did send a error log/description to Hantek/Tekway today.
Zoom in double window mode up to 1000x, with holdoff 100ns to 10s. You can set multiple markers, switch or play between markers.
Not sure if the Zoom is more like Rigol or more like Instek (see instek review), wating for some screenshots from Instek users
to compare it - however it would be hard to compare due dual window function available on Hantek/Tekway devices.Math/FFT:
only CH1+CH2, CH1-CH2, CH2-CH1, CH1xCH2 available.
FFT only Hanning, Flatop and Rectangular with zoom x1 to x10.
In FFT mode no long time memory available anylonger in fw 2.06.2, it was before but i would say good change,
because the DSO wasn't really responsible in FFT with 1m memory mode.
Math/FFT in dual or single window mode availableMeasure menu:
11 values can be measured (Freq,Period, Mean, Pk-Pk, Cycl. RMS, Min, Max, Rise time, Fall Time, Pos Width, Neg Width)
however only 8 displayed at same time.Cursor:
In dual or single window mode available, Time or Voltage but not both at same time.Other:
Timescale 2ns to 40s, i wish 1ns would be available (instek 1ns to 50s)
Avarage sample 4/8/16/32/64/128 (instek have 2 and 256 too)
XY mode with dual window available (XY and XY atr same time)
Ref. A or B can be only saved to internal memory, setup localy or USB, waveforms to USB only.
CSV export currently only 40k samples, more only via PC software.
The DSO is fanless, however you can add fan if you like, there is everythign prepared for.Programming:
Well, all functions can be controlled via USB, but there is no SDK published yet (scheduled for end of Jan 2011).
Also, anyone had experience ordering from Goodluckbuy.com to the US? How long did it take?
ask user g***!, i got my directly from Tekway but from what i understood it was a week (?)
