Objective
To specify the software functionality needed to conduct the component and integrated tests planned for the PDR phase of the FTT contract.

Scope
The requirements in this document are intended to supplement the requirements for the software to be delivered to NMT specified in RD1 and RD2. We will architect a set of software packages to satisfy the superset of these requirements, in order to avoid duplication of effort.

1 Functional Requirements
1.1 Data Logging
· · Logging of metrology readings from DL metrology subsystem Logging of EMCCD camera images · · · · · · · · Full frame at up to 10 Hz frame rate (full frames may be needed for holographic interferometry) Small subframes (e.g. 23 в 23 pixel at 1 kHz frame rate)

Logging of temperature readings ( 1 Hz sample rate) Logging of data entered manually (e.g. theodolite readings) Logging of data from other devices (TBD) Transmission of EMCCD images over Ethernet to test PCI bus conflicts Burst logging: logging of high-sample rate data for short periods at intervals Expected maximum test duration is 20 minutes

1.2 Display
· · The software application that runs the EMCCD camera shall have a built-in image display capability for debugging purposes. It shall be possible to disable this at application startup. Remote display to user in nearby room with latency < 0.1 s(preferably over Ethernet)

1.3 Control
· · · Software shut-off of test heating when specified temperature exceeded Software power-off of EMCCD camera when outside safe operating temperature range Remote control capability for user in nearby room (preferably over Ethernet)
