Pimping old Juniper hardware

If you want a decent JunOS on a SRX with some speed, like 10Gbit/s, then you need much money or some upgraded old hardware stuff.

New Fluke PM6690 counter

Got a new freqency counter, the Fluke PM6690. First, it is also about Spectracom/Pendulum CNT-90 and also about Tektronix FCA3000. These counters are actually relabeled Pendulum CNT-90.

Why fuck you gently, VMware?

Wanted to login to VCSA via web. Password expired, didn’t explicit ask you to ever expire one of my fucking passwords, fuck you.

Tried to connect via SSH, as root, worked, but no fucking shell yet, fuck you.

HP Agilent 33120A AWG Opt 001

There are some units on eBay, but the sellers mostly don’t know and describe them as having the “Opt 001” inside, a.k.a. 33120-80001, a.k.a. 33120-66503.

The Option 001 phase lock/TCXO timebase gives you the ability to generate synchronized phase-offset signals. An external clock input/output lets you synchronize with up to three other 33120As or with an external 10-MHz clock.

Symmetricom Rubidium Standard

This precious thing allows me to connect my GPSDO and have very stable 10MHz output, so all test equipment can use it as reference. The GPSDO itself provides very stable frequency, but has “only” an OCXO inside. So, long-time stability comes from GPS, but now short-time stablility also comes from the rubidium standard and not from the OCXO anymore. So more long- and short-time stability!
