1. / General Features Ø Low skill operation Ø Autotest capability Ø Autotest compatible with Agilent N series instruments Ø Calibrated at multiple wavelengths Ø 1% factory calibration accuracy Ø Supplied with calibration certificate Ø Industry standard connectors – Including SFF Ø Ø Ø Ø Ø 3 High contrast LCD display with backlight Battery life – 190 -360 hours DC power socket Memory USB Computer interface Test tone detection Built in VLS variant (KI 7601) 3 year re-calibration interval 3 year warranty
2. / Models There are two model styles: Ø KI 7600: the most popular. Ø KI 7601: fitted with a Visible source on left hand port There are two Computer interface styles: Ø Early instruments: RS 232 port Ø Current instruments: USB Type A port RS 232 & USB models have minor operational differences 4
3. / Detector Types Choose detector to suit your application. In. Ga. As: Telco & LAN Ø Enhanced In. Ga. As with good response @ 850 nm Ø Power Levels of up to +5 d. Bm Ø Most accurate detector type at Telco wavelengths H series: High power – CATV, DWDM Ø Enhanced H 3 with good response @ 850 nm Ø Power level configurations of up to +27 d. Bm Ø Filtered In. Ga. As Other detector types available for specific wavelength and power requirements. 5
a. / Typical Detector Spectral responses 6
4. / Instrument Care Keep the instrument in its carry case during storage and transport Ø Use only high quality 1. 2 -1. 5 volt batteries. (Do not use lithium batteries) Ø For prolonged storage remove batteries. Ø The instrument is resistant to normal dust and moisture, however it is not waterproof. Ø If moisture gets into the instrument, remove batteries & dry it carefully before reuse Ø Where possible, keep instrument away from strong sunlight. Ø Clean the instrument case using Iso-Propyl-Alcohol (IPA) or other non solvent cleaning agents. Ø Ensure instrument input power rating is not exceeded DO NOT use Acetone or other active solvents as damage may result. 7
5. / Prepare Instrument a) Hand carry strap b) Control buttons c) Power supply – batteries & external d) Turn On / Off e) Fit / Remove adaptors f) Test cord selection 8
a. / Hand carry strap If required, fit provided hand carry strap: Ø Provides enhanced on-the-job instrument care 9
b. / Control buttons Computer Port Hidden Keypad DC Power Turn On/Off RS 232: Back Light USB: Memory store Detector Optional VLS Function buttons λ toggle Battery compartment 10
c. / Power supply - batteries To Install Batteries. Ø Hold instrument in both hands with battery compartment uppermost and with thumbs resting on battery compartment latch. Ø Press latch down and push away from case. Ø Insert batteries. Ø Insert ‘AA’ cells using the supplied AA-C battery converters. Battery life. Alkaline ‘C’ batteries : 360 hours meter, 190 hrs VFL Alkaline ‘AA’ batteries : approx 75 hours meter Low Battery Display. Indicator shows when approximately 10 hours left. 11
Power Supply - external All Instruments: Ø External power supply disconnects the batteries Ø Rechargeable batteries must be removed for charging RS 232: Ø Via the DC power socket USB: DC Ø Via the DC socket or via the USB cord B US Plug Pack Requirements: Ø 2. 5 mm DC power plug Ø 6 -12 V DC @ 300 m. A maximum Ø +Ve pin 12
d. / Turn On / Off 10 minutes auto Off or Permanent operation Push the oval [POWER] button to turn ON or OFF Low battery indicator To defeat auto time out. Hold down [POWER] for 3 seconds during turn ON 13
e. / Adaptor - fitting Industry standard SC adaptors Ø We recommend ceramic/zirconia sleeves Slot to outside 14
Adaptor - removal Current models: Ø Ø Locate quick release button on rear of instrument at base of connector housing Push and hold button in Pull out existing adaptor Fit new adaptor OR Ø Remove as per ‘early models’ Early models: Ø Move adaptor interface to mid position Ø Pull out existing adaptor Ø Fit new adaptor 15
f. / Test cord selection Power meters accept PC and APC connectors. KI 7601 has built in visible laser source (VLS) Ø Must specify visible source to be PC or APC when ordering Instrument ports are colour coded: VLS connector: Ø PC housing: BLUE Ø APC housing: GREEN Specify PC or APC VLS 16
6. / Modes of Operation 4 main modes of operation a) Autotest: Ø automatically toggles between all λs Ø Preferred mode for loss testing as testing time is greatly reduced. Ø Minimises error as meter always displays correct λ. b) Manual: Ø Single λ operation Ø Preferred mode for level monitoring. c) Modulated: Ø Displays incoming modulation frequency d) KITS software: Ø Under software control 17
a. / Autotest Simplest mode for loss testing When receiving light from a compliant source operating in Autotest mode, the meter will auto toggle between λs Ø Power meter receives data which contains wavelength, source serial number and nominal source output power. Ø If power meter not calibrated at an incoming wavelength it will ignore it but remain in sync with other wavelengths. Ø If incoming power level too low at a particular wavelength it will ignore it but remain in sync with other wavelengths. 18
b. / Manual Mode If not in power meter mode Ø Press [Power Meter] To select wavelength Ø Toggle [-/+]. Note: Ø Wavelength toggle is not circular Ø Most meters have the common wavelengths grouped together for speed of access when used in manual mode. E. g. 850, 1300, 1310, 1550, 1625 nm are together 19 [-/+]
c. / Test Tone When receiving test tone or low level modulation Ø Power meter displays modulated frequency and beeps Ø Built in feature cannot be disabled 20
d. / KITS™ Direct Interface to - KITS™ Testing & Reporting software Instrument under computer control Ø Familiar Excel™ User Interface Ø Inbuilt multi language support Ø Memory extract to Excel spreadsheet or CSV file Ø One Click Real Time Data Capture Ø Standards based & user definable analysis Ø Data Logging Ø User Customisable reports Ø Fee for service user customisation service 21
7. / Display Modes a) Absolute d. Bm / Relative d. Br mode b) Setting the Reference c) Log d. Bm / Linear W mode 22
