Itcombinesthe benefitsofd
19、igital scope to measure, store, interpret and communicate the rapid trace, with the benefits of analog scope to measure the widebandwidth, 2 time axis generator, delay sweep and separated TV trigger signal. Itreduces the measurement error,anduses 6% squared type CRT with internal flourescentscale wh
20、ich enables to take thephotograph of observed waveform. (l)High speed optical frequency band width NDconverter installed on each channelsamples theinputsignal at the max. rate of 20MHz samples/sec. Any signal with perfect rcpcatedness can be stored. (Max. 20-60 MHz) This product can be used asanordi
21、nary real time oscilloscope with frequency range between 20and60MHz. (2) Large storage capacity Eachchannelhas 2kW memory. Sinceitcanindicate the waveform composed ofIkWdata, it measures any rapidlychanging transition trace with high accuracy. (3)Waveform save Ithas 1kW memory to save two waveforms
22、stored in each channel. (4) Multi-Function Ithas a varietyoffollowing functions to interpret a wide rangeof signals: - Rollmodefunction to measure low signal. - Average function to eliminate noise from the signal and to measure the pure signal. II (5)Output Ituses both RS-232C interface function to
23、input/outputthe digital datato the personal com puter,andRS-232C toconduct screen hardcopy through digital plotter.Italso interprets and records the stored data. (6)CRTand cursor readout Itcan promptly perform theoperationandmeasurementusingboth the CRT readout function to display the set informatio

47、ing procedures for safety and to prevent damage to the product prior to operating this product. 1-3-1. Line voltage selection Before use, check the voltage. This instrument must be operated with the correct line voltage selector switch setting to prevent damage in reference to table I-I. To change t
48、he line voltage selection: 1. Decide the voltage range and fuse in reference to table I-I. 2. Make sure the instrument is disconnected from the power source. 3. Pulloutthe Line Voltage Selector switch on the rearpanel. Select the arrow mark position of the switch from Table I-I. Slide the arrowmarkt
49、o the desired positionandplug it in. :This producthasthe ground chassis (3 wire power cord is used). Check whether anyotherequipment connecting with this product requires the transformer before use. If so, do not connect the DC/AC or the hot chassis equipment if no transformer is available. Do not directly connect it to the AC powernorto the circuit directlyconnected to the AC power. Otherwise serious personal injury ordamage to this product for a long time without trouble. Table 1
