UNI-T UPO1000HD Series vs SDS800X HD Series
Entry 12-bit HD scopes — the UPO1000HD leads on bandwidth, memory and price; the SDS800X HD on sample rate and noise.
The UNI-T UPO1000HD Series and the Siglent SDS800X HD Series are entry 12-bit HD scopes on a 7-inch touchscreen. The UPO1000HD leads on memory (100 Mpts vs 50), price and warranty, and matches bandwidth at a lower price point; the SDS800X HD leads on sample rate (2 GSa/s), broader standard serial decode and a class-leading low noise floor. Match by bandwidth below.
Both are 12-bit, 7-inch touchscreen entry scopes. The UPO1000HD leads on memory, price and warranty; the SDS800X HD's analog front end is faster-sampling and quieter with broader standard decode.

The bottom line
The UPO1000HD leads on bandwidth and memory; the SDS800X HD samples faster, decodes more protocols as standard, offers an optional logic pod the UPO1000HD cannot take, and lists a little lower. Both are quiet 12-bit front ends — ours is 60 µVrms at the full 150 MHz.
Frequently Asked Questions
Is the UNI-T UPO1000HD Series a good alternative to the Siglent SDS800X HD Series?
Yes. Both are entry 12-bit HD scopes. The UPO1000HD leads on memory (100 vs 50 Mpts), price and warranty; the SDS800X HD leads on sample rate (2 GSa/s), broader standard decode and a low noise floor.
Is the UPO1154HD a good alternative to the Siglent SDS814X HD?
Yes on bandwidth and memory — 150 vs 100 MHz and 100 Mpts vs 50, at the same 12-bit resolution, with a 5-year warranty against three. The SDS814X HD samples faster, decodes CAN-FD and FlexRay as standard, takes an optional 16-channel logic pod the UPO1000HD cannot, and lists a little lower.
Which is better for CAN-FD or FlexRay decode?
The Siglent SDS800X HD includes CAN-FD and FlexRay in its standard decode; the UPO1000HD's standard set is RS-232/422/485/UART, I2C, SPI, CAN and LIN, so for those automotive buses the Siglent has broader standard coverage.
Are UNI-T software options subscriptions?
No. Every UNI-T software option is a permanent one-time unlock — no annual licenses, no renewal fees and no features that expire.
