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
What are the number of sweep points available with the current Bode Plotting function?
November 18, 2021
Here is a list of the current products that support Bode plotting and the maximum number of points available per sweep: SDS1xx4X-E/SDS2X-E Series: 500 points (Linear)/1043/decade (Log) SDS2000X Plus/SDS5000X Series:500 points (Linear)/1024/decade (Log) SDS6000A Series: 751 points (Linear)/1576/decade (Log)
Why do the SP3050A passive probes that come with the SDS6000A have a 2 GHz only label?
November 1, 2021
The SP3050A 500 MHz probes for the SDS6A are adjusted to best match the front end of the SDS6A series of scopes. They have a different response from the same models that are included with other SIGLENT scopes, including the SDS5X. The label is used to distinguish between the two types of SP3050A probes. The … Continued
How can I estimate the minimum current measurement of a current probe using an oscilloscope?
September 27, 2021
Here is a quick method for estimating the lowest current measurement that is possible with an oscilloscope and current probe. This is especially useful when the datasheet for a probe may not show the minimum current that can be measured or it may be missing the noise floor value. For this note, we will be … 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
