The signal edges are invis- ible during this adjustment. Its voltage rat- ing is max. If no stable trigger point is found with normal triggering with extremely complex composite signals even after slowly rotating the LEVEL knob, solid trigger can be obtained in many cases by operating the variable time control knob on the time switch.
The chop mode is not effective in the memory mode. LED indicates operating condition. Single, X-Y operation, addition: The DC position should only be used with a series-con- nected attenuator probe or at very low frequencies or if the measurement of the DC voltage content of the signal is absolutely necessary.
The dot density is high max. Switching the oscilloscope off and on at short intervals stresses the cathode of the CRT and should therefore be avoided. For additional information, see the Global Shipping Program terms and conditions – opens in a new window or tab. The HZ65 oper- ates with all scopes, which can be switched to X-Y operation ext.
Switch test signal coupling to AC or DC. However, it is generally expedient to set the white line on the cap of the Y-POS. However, the visible signal on the screen can be expanded by pressing the X-MAG. Therefore the derating curve of the attenuator probe type concerned must be taken into account. Time measurement with time fine control at right stop CAL.
The time base is set so that several wave of the modulation frequency are visible. At the left stop, the time coefficient set on the switch in analog mode is at least 2. Thus signal frequencies down to 0. Therefore, if the voltage loss due to the attenuation of the probe can be compen- sated by a higher amplitude setting, the probe should always be used. It must then be pushed in.
The time coefficient can be changed within a large range as required. Two sockets provide for quick testing of the 3 junction areas in any small power transistor.
It is therefore particularly suitable for measuring small hum voltages of mains rectifiers or stray low frequency pickup in a circuit. Breaks or peaks glitches next to the edge are also not taken into account. Decreases deflection by a factor of 2.
Trace rotation TR Despite Mu-metal shielding of the CRT effects of the earth’s magnetic field on the horizontal trace position cannot be entirely avoided.
The correct knob for this must be found by trial and error. It provides greater picture intensity for certain signals. Image not available Photos not available for this variation. Since the real time mode has priority in this case its control adjustments are deter- minedthe memory images must be read in beforehand. Holding the casing firmly, pull out the chassis by the front panel molding. Other components are connected by using 2 banana jacks.
It goes out at the instant of triggering.
