ADJUSTMENTS
ADJUSTMENT OF BUS-TUNER : 880-2091E
This adjustment sets some values of the tuner.The adjustment
data is written in EEPROM(IC605).The special jig and software
are necessary for this adjustment.
* CeNET-analyzer
* Personal computer
*SG
* Adjustment-Software:Adjustment system for DSP N217
with CeNET(Ver.Y4-S024-103-20060623)
Preparation
1. Installation of software
Execute the windows installer package in the set-folde
of the writing E2P.
2. Connection
1) Connect CeNET-analyzer to the unit with the CeNET-cable.
2) Connect CeNET-analyzer(MASTER/SLAVE side) to the
PC with the serial crossing cable.
3) Connect POWER-lead of CeNET-analyzer to the
POWER-lead of the unit.
4) Connect the antenna to the unit.(FM-ANT for first adjustment)
5) Turn on CeNET-analyzer,and press the RESET-button of it.
Set up the software
1) Click [ADJ_DSP].
2) Click [open Comm PORT].(To open the COM port of PC)
3) Click [Initialization of JIG].(The BUS-analyzer sounds)
4) Click [Incoming connection].(The unit is recognized to
the BUS-analyzer)
The data is displayed, and the display changes regularly.
PRN data writing
1) Click [prn FILE LOAD], and select PRN-FILE.
2) Click [EEPROM WRITE], the PRN-data is write in EEPROM
of the unit.
Adjustments
1. FM S-meter
1) Set SG output to 65dBuV.(FM)
2) Click [Adjustment] of "FM S-Meter".(Wait until the value stops.)
2. FM IF-Count
1) Click [Adjustment] under "FM IF-COUNT".(The FM-IF-
Offset data of EEPRON is effective.)
2) Click [Check], and confirm the display is within +/-500.0.
3. Set up AM IF Offset data
* Exchange the antenna for "AM-ANT-dummy"
1) Click [Adjustment] under "AM IF-COUNT".(The AM-IF-
Offset data of EEPRON is effective.)
2) Click [Check], and confirm the display is within +/-500.0.
4. AM S-meter
1) Set SG output to 70dBuV.(AM)
2) Click [Adjustment] of "AM S-Meter".(Wait until the value stops.)
Finally, push the reset button of the unit.
When computer continues to freeze, click [RESET] of "MENU", and
readjust the lost adjustment point.IF not returning, press the
RESET-button of CeNET-analyzer.and restart adjustment from
the first step.
