The Model E115-L is a conventional, wide purpose dc-bias FLL-unit designed for use with LTS- dc-SQUIDs.
The Model E115-DB is a universal ac/dc-bias FLL-unit designed for both of HTS- and LTS dc-SQUIDs
The E115-L FLL-unit hase the following parameters:
| internal noise level of the preamplifier | 0.7 nV/ÖHz. |
| modulation frequency | 100 kHz (max. 400 kHz) |
| number of the feedback ranges (current feedback and flux feedback) | 2 |
| transfer function of the feedback circuit | 1 V/F0, 0.1 V/F0 |
| bandwidth of the dc-SQUID electronics | 50 kHz (max. 200 kHz) |
| dynamic range | 130 dB (max. 160 dB). |
| slew rate | up to 500000 Fo/s |
The FLL-units E115-DB have the following parameters:
| internal noise level of the preamplifier | 1 nV/ÖHz. |
| modulation frequency | 200 kHz (max. 500 kHz) |
| ac-bias frequency | up to 250 kHz |
| number of the feedback ranges | 2 |
| transfer function of the feedback circuit | 1 V/F0, 0.1 V/F0 |
| bandwidth of the dc-SQUID electronics | 50 kHz (max. 200 kHz) |
| dynamic range | 130 dB (max. 160 dB). |
| slew rate | up to 100000 Fo/s |
As usual, the FLL-units contain an analog and
a digital part. The analog part uses a conventional null detector circuit and incorporates
a magnetic flux feedback and circuits for adjustment of the SQUID parameters. The digital part
is based on the processor and makes it possible to switch the adjustment and operation
modes of measuring channels when the system is controlled from a personal computer. The use of
processors makes new electronics very flexible in terms of programming, and provides
for convenient incorporation in a big modules for constructing of multichannel systems.
We propose to the market also the multichannel FLL-units. They are based on both models E115-L and E115-DB of the FLL-units. 4-, 8-, 12-, 16-, 24-, and 32-channel modules were designed especially for a new types of MCG- and MEG- measuring systems.
