Cross-reference of Oscilloscope Serial Decoding equivalents to Tektronics MDO3 packages

December 3, 2021

Here is a cross-reference of SIGLENT oscilloscope serial decoding features compared to the Tektronics MDO3 options: Tek MDO3MSO: 16 channel logic analyzer function. The SIGLENT equivalent is optional license SDSxxxx-16LA, where xxxx represents the model (SDS1000X-E, SDS2000X-E, SDS2000X Plus, SDS5000X, or SDS6000A series of oscilloscopes) and hardware (SPL2016 for SDS2000X Plus, SDS5000X, and SDS6000A series/SLA1016 … Continued

SDS2000X Plus 500 MHz bandwidth upgrade details

December 1, 2021

The SIGLENT SDS2000X Plus series of oscilloscopes have a 500 MHz bandwidth upgrade option. 500MHz bandwidth is available in the following cases: Only one active channel (C1 or C2 or C3 or C4) Two channels (Either C1 or C2) & (Either C3 or C4) When 500 MHz bandwidths are available, the display will indicate “Full” … Continued

Do your instruments support UDP communications over LAN?

August 5, 2021

Not at this time. Many instruments support communication via sockets (port 5025) and telnet (port 5024) but the port numbers cannot be changed. If you use VISA, you can implement LAN via TCP/IP, which does not need a port number. Here is a listing of current SIGLENT instruments with Socket and Telnet Support.

How to check available internal memory?

July 29, 2021

Simply access the Save/Recall menu for the instrument in question and select Local. The menu will show used/total amounts. Here, the SDG6X has approximately 83 MB and the SDG1X has 85 MB of memory:

Bode plot memory depths

July 19, 2021

Here is a table showing the various memory depths used in the Bode Plot feature Product series  Max memory depth  SDS1xx4X-E   140k  SDS2000X-E  140k  SDS2000X Plus  100k  SDS5000X 125k

Why is the Bode Plot start frequency minimum 10 Hz?

June 23, 2021

The minimum start frequency is set to 10 Hz because of the extended acquisition time required to collect enough data to ensure a useful level of measurement accuracy. If the low limit was 1 Hz, the scope would need to test 10 cycles (to maintain specified accuracy), so the time base will be 10 s/div. … Continued

SDS2000X Plus and SDS5000X Default Logic Levels

May 17, 2021

The SDS2000X Plus and SDS5000X series oscilloscopes have default threshold and trigger values for the MSO/Digital channels listed below: TTL = 1.5V CMOS = 1.65V LVCMOS33 = 1.65V LVCMOS25 = 1.25V
