Information
PM 3335, 60 MHz, 20 MS/s Digital Storage Oscilloscope
Analog oscilloscope plus full function Digital Storage Oscilloscope
20 MS/s synchronous real time sample rate on each channel
60 MHz analog bandwidth
Deep SK bytes x 8-bit waveform acquisition memory even at max sample rate
Second reference memory for comparison of waveforms
AUTOSET for instant on-screen trace display
Standard cursors for many on-screen measurements
GPIB/IEEE-488 and RS-232C interface options
Two Scopes in One
Philips PM 3335 sets a standard in performance and economy. This instrument is two professional scopes in one: it operates as a real time 60 MHz analog oscilloscope and at the touch of a button, becomes a full function digital oscilloscope for advanced applications. Now, for the first time in a cost-effective scope, you have the power for digital capture and analysis of exclusive
single shots with a full 20 MS/s sample rate on each channel simultaneously. Unlike some scopes in this class, the full . sample rate is maintained for all channel combinations, giving a single event resolution of 50 ns for both channels.
Repetitive signal analysis is also posstble up to 60 MHz in analog oscilloscope mode. A x10 expansion allows 5 ns sweep speeds for detailed viewing and furthermore, with the 100 MHz trigger bandwidth, you have a higher trigger sensitivity
over the full range.
