带宽100MHz 双通道 光标测量 频率直读
The Hitachi portable read-out oscilloscope provides
measurement reliability and ease of operation by employing a
microprocessor. The major features are:
(1) Measurement information display
The measurement information including the sweep speed, the delay time, the UNCAL display, and the voltage sensitivity of the vertical axis (Cursor Readout type only) is alphanumerically displayed on the CRT. Since troublesome setting operation procedures are elimi-nated, an operator can concentrate on the displayed data for measurement.
(2) Measurement value display (Cursor Readout type only)
The distance between the two cursors displayed can read out the following;
△V: Voltage between the reference cursor and the delta cursor
△T: Time between the reference cursor and the delta cursor
1/△T: Reciprocal of the time The displayed data eliminates troublesome and time consunling calculation procedures. Moreover, miscalculation of the scales is completely 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 cycles approx. is displayed.) The time base range is automatically changed to a corresponding change in input signal period.
(4) Frequency counter (Cursor Readout type only) The A TRIG signal frequency can be measured.
(5) 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.
(6) Channel input Quad channel input (V-1585, V-1085 on
Besides CH1 and CH2, CH3 and CH4 provided with 0.5 V/ DIV and 0.1 V/DIV range selection capabilities are provided for easy digital signal measurement.
V-1585, V-1085, V-1565, V-1065A, V-1560, V-1060
DC-100MHz (2mV/div: DC-20MHz)
V-695, V-665A, V-660
DC-60MHz (2mV/div: DC-10MHz)
(8) High sensitivity
High sensitivity of 2 mV/div is provided.
(9) Internal graticule
Internal graticule lines eliminate parallax-viewing error between the trace and the graticule lines.
(10) Delayed sweep
With delayed sweep, a portion of the signal can be magnified for more accurate measurement and time comparison. The delay time is digitally displayed on the CRT.
(11)Auto trigger Level
Auto measuring of trigger level is employed, so that trigger level range is matched to the trigger signal for maximum trigger sensitivity and stability.
(12) TV triggering
Exclusive TV sync separator circuit technology provides stable TV signal measurements on fields, frames and lines.
