Reference Designer

The Siglent 1000 series offer one of the best price performance and we have no hesitation to recommend it to any one looking for decent oscilloscopes at reasonable price. It comes is DL, CNL, CML CFL and X Series. The entry Level DL Series has sampling rate of 500 Mega Samples/sec that increases to 1 GSamples/ Second for CNL and CML Series and to 2 GS/sec for CFL Series. The CML Series has higher memory depth of 2 Million points. The X Series is an entirely new design and offer significantly higher memory depth.

Let us take a look at some to the parts used in its design. The parts used are based upon the SDS1202X part which is 200 MHz part with 14M depth. The parts used should apply to all of the SD1000X series. The other series may have similar but slightly different design.

A/D COnverter HAD 1511

Hitttite HADCAD1511 is used for A/D conversion. It gives out 1 Gig Samples /second @ 8 bits.

Memory Hooked to acquisition FPGA

Micron's 64 Mb part MT41J64M16JT-15E:G is attached to the acquisition FPGA.

1. Processor Analog Devices ADSP-BF526

The Analog Devices Blakfin DSP processor ADSP-BF526 is used, likely for the waveform processing and math function and other similar stuffs. It also connects a USB port and Ethernet port.

2. Memory attached to Processor

Micron 48LC32M16A2 is attached to the Analog Devices processor.

2. Lattice FPGA LCMX0640C used for Display

A separate Lattice FPGA is used for Display.

Let us look at the different part numbers and corresponding features

Besides that it also has 4 Channel variations of SDL000CFL Series

Table : 4 Channel SDL1000CPL Series

The 1000X Series increases the memory depth to 14M. The Suffix S in part numbers add Waveform generation function to these Oscilloscopes ( and yes - an extra $200).
