General Description1
1000000
Introduction 1.1
0 The introduction of a new family of high-performance cryogenic probes represents
a major step forward in NMR instrumentation.
Developed in order to cover a huge number of chemistry applications, the Cryo-
Probes offer outstanding performance with respect to signal-to-noise and mea-
surement time.
This manual covers:
•Installation of the rf wiring for different types of CryoProbes
•Software description
•Technical data
•Some service informations
Most of the information given in the ‘HPPR Technical Manual‘ (Z31075) and
‘HPPR/2 Technical Manual’ (Z31559) remains valid for the HPPR CRP MOD-
ULEs.
Features 1.2
0 •Practical and easy-to-use.
•Integrated cryocooled preamplifiers, filters and t/r-switches make maximum
use of the significant signal-to-noise improvement in a cryogenic cooled signal
detection system.
•Additional functionality is offered in conjunction with the HPPR CRP ASSEM-
BLY as for example:
- Computer controlled signal routing between the CryoProbe and the
HPPR CRP MODULEs respectively HPPR/2 MODULEs
- Improved spectral purity of the rf pulses by using the built-in filters of the
HPPR CRP MODULEs (HPPR/2 MODULEs)
- Probe tuning of all nuclei
- PICS (Probe Identification System)

RF Wiring for a CP DUL C/H-D or CP DUI H/C-D (HPPR CRP)
Technical Manual Index 003 Bruker BioSpin 7 (33)
RF Wiring for a CP DUL C/H-D or CP DUI H/C-D (HPPR CRP) 1.4
0 The standard HPPR CRP ASSEMBLY for a CP DUL C/H-D or CP DUI H/C-D
consists of the following parts:
•HPPR CRP COVER MODULE
•HPPR 1H CRP MODULE
•HPPR 2H CRP MODULE
•HPPR X-BB19F 2HS MODULE
•HPPR 13C CRP MODULE
The HPPR CRP MODULEs are almost identical to the well known HPPRs used
for a conventional probe with exception of partly different filter characteristics and
additionally included functions used for the CryoProbe. However, every HPPR
CRP MODULE may be used for either CryoProbe operation or with a convention-
al probe. For CryoProbe operation pull the ribbon cable connectors at the JUNC-
TION BOARD of the HPPR X-BB19F 2HS MODULE!
NOTES:
1. The HPPR XBB19F 2HS MODULE is used ONLY for operation with a conven-
tional probe.
2. In general, no external filters are required between the HPPR MODULEs and
the CryoProbe (exeption: connetion from CP 13C RF OUT to HPPR 13C RF IN).
