This project will be to build a 1U Rubidium 10MHz Frequency Reference for the lab, using an Efratom LPRO-101 reference module. This will be used as our house 10MHz reference, initially to run the system timer of tick.hacklab.to.
Status
- 2012-01-01: Breadboarded up the buffers for the monitoring signals using an LM324 we had laying around, then committed the first part of the signal conditioning board to perfboard.
- 2012-12-31: Started planning/putting together specs for the finished product.
Desired Features / Specs
- Half-width 2U Enclosure (likely Hammond RMCS9038BK1)
- Front:
- Analog round meter for Lamp Volts (0-15V w/ 6-9V normal range, 3-14V warning range)
- Analog round meter for VCXO Volts (0-15V w/ 0.5 - 13.3V normal range)
- Analog edgewise meter for system temperature
- LED for Atomic Lock
- LED for Overheat
- Back:
- Fused IEC C14 Power Input
- 10MHz Buffered Sine 0.5V Output
- 10MHz Buffered TTL 5V Output
- Internal:
- Power supply (19V @ 1.75A ignition, 1.25A warmup for ~5mins, 0.5A running)
- Buffering for Sine output
- Buffering/conversion to 5V TTL output
- Signal conditioning board, containing:
- Buffering for the Lamp Volts meter
- Buffering for the VCXO Volts meter
- Buffering for the Atomic Lock LED
- Temperature monitoring circuit
- Front:
