Scope SETUP can be activated using SETUP SOURCE key. Following screen will appear:
Output voltage of the SCOPE option can be triggered by external signal connected to coaxial BNC
connector on the front panel. Square wave signal with amplitude over 1 Vpk is expected. Input resistance
of the triggering input is 50 Ω. Only one parameter selection is available for triggering signal, Trigger
Ratio.
To change setting push the SETUP key in SCOPE function, chose item Trigger Ratio and select one of
values Off, /1, /10, /100. The number indicates nominal ratio of the frequency between triggering and
output signal.
Scope option has two impedance configurations of HF coaxial output connector, 50 Ω and Low Z output
impedance. Requested setting can be selected in Scope SETUP, item Impedance. In Low Z mode output
impedance is close to zero Ω, typ. < 1Ω, in 50 Ω mode is output impedance set to 50 Ω ± 2 %. Setting
of output impedance is indicated in the field SOURCE on the display using labels „LOW Z“ and „50
Ω“.
Last item in the SETUP menu is selection of displayed units. Change of unit can be performed also in
individual subfunctions using soft key Ampl. Unit.
Calibrator can simulate various, most frequently used temperature sensors, both resistance RTD type
and thermocouple TC type. The function is accessible after function selection key OPTION pushing
followed by selection of type of sensor.
