Hi again,
This time, I am in the market to buy my first oscilloscope as a hobbyist. I am in the UK looking at stores in Europe. I work mainly on Arduino type projects (especially IoT). I am looking for:
- Budget: £350 - £550
- Sampling rate: At least 1GSa/s for single channel
- Bandwidth: At least 100MHz
- Channels: At least 4
- Record length: At least 10Mpts for single channel
- Segmented memory: I reckon I don't need it if I have enough record length (at least 20Mpts)
- An intuitive and easy to use interface. Touchscreen combination with knobs and mouse support would be best, otherwise an intuitive "knob" interface.
- Compact in size. In general, I prefer wider (or taller) than deeper equipment due to my limited space.
- Not a loud fan (but I have no problem fixing that if needed)
- Network connectivity (LAN, WiFi) is preferable over USB
- Don't need integrated bus decoding and/or MSO functionality because I have a separate Logic Analyser, but would be nice to have
- Don't need integrated Signal/Waveform Generator because I am planning to purchase a separate one
Here is the shortlist I came up with (in the pros and cons I am highlighting the differences between the products):
1. RIGOL DS1054Z (hacked to 100MHz) - £370+ Cheap
+ Comes with all software options unlocked
- Low Waveform Capture Rate of 30,000wfms/s
- Needs to be hacked for 100MHz
- A bit old and a tiny bit sluggish according to reviews
- The fan is a bit loud
2. Siglent SDS1104X-E - £430+ I have a Siglent power supply, so I have used the brand before and trust them
+ Option for Signal Generator and/or MSO capabilities (I don't care much about this though)
+ Doesn't need to be hacked for 100MHz but can be for 200MHz
+ Can do 1 GSa/s for 2 channels
+ Highest Waveform Capture Rate of 100,000wfms/s - 400,000wfms/s
+ Embedded web server means I don't need to use additional software to control remotely
- Many options are locked but can be hacked
- The fan is a bit loud
3. GW INSTEK GDS-1054B (hacked to 100MHz) - £440+ Separate knobs for each channel
- Needs to be hacked for 100MHz
- Too big for my workspace
4. Micsig STO1104C - £485 or £545 with battery plus other accessories+ Form factor is ideal for my bench
+ Touch screen with knobs is the perfect interface for me (also mouse support)
+ Android system with very high potential of expansion in functionality
+ Doesn't need to be hacked for 100MHz
+ Much easier to use picture functionality and has video recording
+ Battery operable (don't need this or any portability for that matter but nice to have)
+ WiFi connectivity
- External power supply
- Has external control support, but is through a software (I prefer the Siglent webserver)
All in all, I am leaning almost entirely towards the Micsig. Even though it does not have the best specs for the money (I believe the Siglent does), as a first-time oscilloscope user, I can see really like using the Micsig over more traditional scopes and also the Android system it has tells me that there is a very good future for it. Even though it is the most expensive, the difference is small enough for me to justify it.
Any thoughts? Any scopes I missed that could fit the bill well? Perhaps some specs I overlooked that matter much more than I thought?
TL;DR: Rigol is cheapest, GW Instek is too big, Siglent has the best specs, Micsig has good specs with my favourite form factor and interface with decent specs so I am leaning towards it.
