Performance Check – TekRanger
Introduction
These performance checks ensure that the TFS3031 TekRanger is operating
properly and conforms to instrument specifications as listed under Specifications
– TekRanger (serial nos. below B052000) in Section 1. This perrformance check
procedure applies to TekRanger instruments with serial numbers below
B052000. For the TekRanger 2 performance check, refer to section 4.
The performance check should be done after an instrument has been serviced.
If you are unfamiliar with how the TFS3031 works, it may help to review the
TFS3031 User Manual or Reference Card before doing the performance check.
If the MAIN31 board or one of the optical module assemblies is replaced,
performance of the TFS3031 must be characterized to ensure optimum perfor-
mance of the event-detection algorithms. This is done by using the performance
test software housed on a floppy disk. See Table 1–127 on page 1–105 for the
performance test software part number.
An IBM-compatible PC (386 or better) with a serial port is required for this
characterization. To use the performance test software, see the instructions in the
readme file that comes with the software package.
