Long days in the lab...

I have spent the last 2 days processing shallow snow and firn cores in the lab, this is the last one (for now). Really nice datasets coming out, but a lot of concentration required.

At least I have a great view (when I remember to look up).

Review of the Fluke 1953A counter/timer shows it is fully working as hoped (operating under local and remote control.) Verified all inputs and operations via GPIB remote control with a simple LabVIEW program. Have a few more esoteric tests to run in near future, but for now, it looks great for a counter/timer from the 1970’s. #TestEquipment #LabVIEW #NotTimeNut

@alcea moooment. Ich habe mehrere Programmiersprachen gelernt, und gerade zum ansteuern von Geräten und zur Darstellung von aufgenommen Daten ist LabView aber sowas von viel einfacher als alles andere. Es eignet sich für ganz viele Dinge nicht so gut (und deshalb kann man zum Beispiel Matlab Code einbinden, statt den mit LabView zu programmieren), aber für die Dinge die es tun soll ist es super (und teuer).

Es ist auch mega einfach zu lernen: Datenströme werden als Draht dargestellt, und jedes Kästchen ist eine Funktion, die mit Inputs (kommen von links) bestimmte Outputs (gehen rechts raus) erzeugt. Rahmen um irgendwas herum sind Strukturen wie Schleifen, cases, ...die die entsprechenden Code Blöcke unter Bedingungen ausführen. Das ist wirklich straightforward, wenn man nicht gerade einen chinesischen Screenshot nimmt.

(Denkt aber es wär eine Programmiersprache 🙈)

Rainy day in EN52 Chicagoland - time to setup and test a Mini-Circuits ZX47-55 RF detector module to see if working or not. Measured DC Out vs 100 MHz RF level In and DC Out at -20dBm In while sweeping from 0.1 to 6 GHz. Result: It works as a RF detector module but DC output is not easy to use (want dBm, got neg-slope DC mV instead). Might make a LabVIEW program to display/chart dBm with Digilent AD3, or maybe write code for a standalone Arduino w/ display showing dBm… #RF #LabVIEW #Arduino
