How to license DSG815/830 options Insert the following parameters in the usual license generator : Forever Options: AAAB (0x00001) - DSG800-PUM Pulse Modulation & Pulse Generator AAAC (0x00002) - DSG800-PUG Pulse Train Generator Public Key: 6673BBC777EA4D (Key taken from the current FW. Those interested will have to calculate the Private Key as homework.) ;) As always, insert the licenses with SCPI command :SYSTem:LKEY. Edit: Corrected the options' hex designations. |

I made a breakout board to explore the the OCXO option for the DSG-815 (option OCXO-B08). https://beyondmeasure.rigoltech.com/acton/attachment/1579/f-0644/1/-/-/-/-/DSG800%20OCXO%20User%27s%20Guide.pdf Pinout: 1: GND 2: Detect input 3: slot 4: slot 5: VCC 6: CLK input 7: VCC 8: VCC 9: GND 10: Detect output VCC is 6.515 V when the signal generator is plugged into mains. This is higher than I expected as the OCXO-B08 datasheet specifies 5.00 V +/- 0.25 V. It didn't drop much with a 220 ohm resistor (~30 mA). Will have to find a bigger resistor to test at loads specified in datasheet (300-600 mA). Detect output (pin 10) goes from 0 to 3.3 V when the signal generator is turned on. When I connect this pin to Detect input (pin 2) through a 1 K resistor Syst > Information > System Info reports the option OCXO-B08. Interestingly, there's no error message even though I don't feed an external clock signal yet. CLK (pin 6) was the only pin left. Not tested yet. The pitch of the pins on the edge-connector is 1mm, 10 positions with a key slot (which is counted as a position). A matching connector is Samtec 1mm Mini Edge Card Socket Vertical, part number MEC1-105-02-F-D-EM2 or MEC1-105-02-L-D-EM2. https://www.samtec.com/products/mec1-105-02-f-d-em2 https://www.samtec.com/products/mec1-105-02-l-d-em2 The dimensions of my breakout PCB are 32 mm x 50 mm, 1.6 mm thickness. It turned out to be about 3 mm too long, so 32 x 47 mm would be the correct size. The size of the original OCXO is likely 25.4 x 25.4 mm. There are no good images of the OCXO-B08 to be found, but OCXO options for the DSG3000 (OXCO-A08) has similar specifications. Some images for that option show an OCXO from DAPU with part number O22B-G445. Unfortunately, that part number doesn't quite match with the numbering-scheme on DAPU's website: https://www.dptel.com/Products/ProductLevel4/2899 Any thoughts about VCC being 6.5 V? Any suggestions for a suitable OCXO for this application? |

Using this information one can easily do a random mistake like this: DSG815 -> DSG836 :popcorn: |
