Table8.1: Parameter and Technical Data
General Note: Any of the values listed above may change without notice.
1. Values from -1000.0 to +1000.0 degrees are accepted, however the actual phase is
evaluated modulo 360 degrees.
2. The actual range depends on the hardware code and on the frequency: The first series of
RF boards (HW code 0) had a range from -50 to +10 dB, the next following series (HW
code 1 and higher) had a range from -60 to +0 dB. For frequencies of 600 MHz and
above, this range has been extended (-60 dB to +10 dB) on the hardware versions 6 and
higher.
3. This value is used for static drift compensation with manual evaluation/definition of the drift
rate (called Manual Drift Compensation, e. g. in solids configuration). Static/manual drift
compensation is active while the lock is not sweeping.
4. Maximum Noise between 0.01 Hz and 10 Hz
5. Minimum range of -3 dB point
8.3 Configuration and Wiring
The ELCB is plugged into Slot 10, see Figure 4.3 [}31] . The drawing below shows the front
panel of an ELCB with the LED‘s and connectors. For proper operation with TopSpin, at least
the Ethernet, the 10 MHz reference clock and the RCP input have to be connected
accordingly.
There is a dedicated connector for the communication with an optional SampleCase
automated sample changer.
