模拟示波器 V-1060
100MHz/2mv/5ns/2通道/CRT读出
厂家: 日本日立
尺寸: 27×13×45cm
重量: 4kg
The Hitachi portable read-out oscilloscope provides measure-ment reliability and ease of operation by employing amicroprocessor.
The major features are:
(1) Measurement information display
The measurement information including the sweep speed, thedelay time, the IJNCAL display, and the voltage sensitivity ofthe vertical axis (V-1065 ,V-1065C and V-665 only) is alpha-numerically displayed on the CRT.
Since troublesome setting operation procedures are eliminat-ed, an operator can concentrate on the displayed data formeasurement.
(2) Measurement value display (V-1065, V-1065C, V-665 only)
The distance between the two cursors displayed can read out the following;
△V : Voltage between the reference cursor and the deltacursor
△T : Time between the reference cursor and the deltacursor
1/△T: Reciprocal of the time
The displayed data eliminates troublesome and time consumingcalculation procedures. Moreover, miscalculation of thescales is compley avoided.
(3) Automatic time base range setting
At a press of the AUTO button, an optimum time base range is automatically set.(A signal period from 1.6 to 4 cyclesapprox. is displayed.)The time base range is automatically changed to a correspond-ing change in input signal period.
(4) Trigger lock
Since complicated pulse train waveforms are hard to trigger on, performing the trigger lock function enables sweep independent triggering. The "sweep time plus holdoff time"is fixed and a stable trigger is obtained at any time range.
(5) Bandwidth
V-1065,V-1065C,: DC-100 MHz from 5 V/div to S mv/div
V-1060 DC-20 MHz at 2 mV/div
V-665, V-660 : DC-60 MHz from 5 V/div to S mv/div
(6) High sensitivity
DC-10 MHz at 2 mv/divHigh sensitivity of 2 mV/div is provided.
(7) Internal graticule
Internal graticule lines eliminate parallax-viewing errorbetween the trace and the graticule lines.
(8) Delayed sweep
With delayed sweep, a portion of the signal can be magnifined for more accurate measurement and the windows of delayed sweep(B) is indicated on the main sweep(A) with cursors.
(9)Auto trigger level
Auto measuring of trigger level is employed, so that trigger level range is mathed to the trigger signal for maximum trigger sensitivity and stability.
(10)TV triggering
Exclusive TV sync separator circuit technology provides stable TV signal measurements on fields, frames and lines.

1 .2 Frequency measurement
When MEASURE is selected by the SELE*OR switch, the * cursor is displayed on CRT. Then press the SELE*OR switchthree times to display FREQ at the upper part of CRT.
The frequency counter is interlocked with the triggering andthe measurement starts from the triggering point.
Consequently, any special frequency having complex waveformscan be measured by changing the trigger level.
For example, when a signal as illustrated below is applied,the frequency of the entire waveforms can be measured whentriggered at point A. When triggered at point B, thefrequency of a pulse with large amplitude can be measured.
Note : When not triggered, the measurement can not be per-formed, since the counter is interlocked with thetriggering. In the non-triggering mode or in case ofthe input signal less than 20 Hz, the message"FREQ..." is displayed.
(B) Memory backup
The panel setting data is retained for move than 48 hoursafter turning off power. It is not needed to perform thesame panel settings again even on the day after tomorrow.
(C) Other specifications
Same with those of the V-1065.
