1. Advanced display facilities for realtime analysis up to 100MHz Multi source triggering Trigger view as fifth channel Simultaneous display of MTB and DTB Portable with battery operation for field use The PM 3264 offers a unique solution to many timing problems in digital electronics Simultaneous display of 4 or 5 input signals prow lt 2 quick and convenient method for reat naiysis of digital signals both at component and system level A versatile deflection system provides many user benefits For example any com bination of up to five input signals and two different modes can be selected by push buttons The sensitivity of the channels includes 2mV div up to 400V per screen using the standard 1 10 attenuator probes A fle in iggering system allows the main an gt i time bases to be triggered independently by any of the four input channels Also an external trigger and composite trigger are provided The alternate time base facility permits a quick reference for magnified displays with respect to the original waveform The multiple trace display demands a CRT with very high light output Philips has designed aero tube with 17kV pda which provides ain san adequate sharp bright spot With aii ine foregoing facilities the PM 3264 remains a typically compact portable oscilloscope which is also extremely simple to use The various facilities are summarized as fo2. setting and power cord option In such cases purchase orders should specify one of the following options Universal Euro 220V 16A Option 001 North American 120V 15A Option 003 United Kingdom 240V 15A Option 004 OPTIONAL ACCESSORIES PM 8924 00 PM 8924 20 PM 8928 00 PM 8931 00 PM 8960 03 PM 9381 PM 8976 PM 9366 PM 8980 PM 8991 Oscilloscope trolley PM 8992 66 Accessorypouch Passive probe 1 1 1 5m Passive probe 1 1 2 5m HF passive probe 10 1 1 5m 7 Passive probe 100 1 2pF 1 5m 19 inrackmountadapter _ Oscilloscope camera Camera adapter for fixed use Collapsible viewinghood Long type viewing hood PM 8999 Stand ae PM 8901 Batterypackfor3hourscontinuqus Tea ee i PM8910 Polaroid anti glare filter A eat ae
