When using the DSA815-TG to get a spectrum output from a HF transmitter, seen a strange spurious signal in the area of 14.3 MHz. Hi, Got a strange problem with the DSA815 and would like to see if anyone else is observing it.
I hope this post helps answer some of the sought after questions regarding the *new* DSA815-TG w/ 1.18 Firmware. Of course I also still have functioning the 10Hz RBW that came activated from the factory with the 1.18 Firmware. So I will definitively state that the *never_ending_trial_time_mod* does indeed still work with the *new* 1.18 Firmware and ver. Each time I reboot the SAME 13hrs 9mins xxseconds is restored. I now have 13hrs 9mins xxseconds remaining forever.
Switching on the switch effectively shorts together Pin7 and Pin8. I did NOT *lift-up* Pin7 when I connected the *jumper wires*, it remained soldered to the pcb. I have access to the switch from outside of the unit with a toothpick, in case I need to run updates, etc. At the suggestion from CombatWombat71, I went ahead and opened the DSA and ran two thin jumper wires, one from Pin7 and the other from Pin8 on the ICU1105 to a small slide switch mounted on the RF-shield. I was beginning to get desperate because my *Trial Time* was about to run out. So I am using 1.18 Firmware and version 1.04 Boot. I have a *new* DSA815-TG which was purchased the end of last year, 2016. Good day All: OK, figure I'd post my latest finding regarding the *never_ending_trial_time_mod* with a FRAM Write Protect Switch.
