Tabor 8020 - General Information

Marker Output: Same as logarithmic sweep
Sweep Stop Resolution: Same as Frequency resolution
VOLTAGE CONTROLLED OSCILLATOR (VCO) CHARACTERISTICS
Input Impedance: 10 Kohms +/-5 %
Sensitivity: 0 V to -10 V +/-20 % produces frequency change 1/1000 from main frequency when
main frequency is set to 2000 counts
Bandwidth: DC to 70 KHz
FM Sensitivity: 0 V to 100 mV modulates to 1% deviation from center frequency
PULSE / RAMP CHARACTERISTICS - MODEL 8021

PWM (pulse width modulation):
Mode: External PWM
Input: Via front panel PWM IN BNC connector
Input Impedance: 10 Kohms +/-5 %
Sensitivity: +/-5 V produces >10 % pulse width change when instrument is set to 100 counts
AM CHARACTERISTICS - MODEL 8022
Mode: External AM
Input: Via front panel AM IN BNC connector
Input Impedance: 10 Kohms +/-5 %
Carrier:
Waveform: All available front panel waveforms
Level Range: Continuously adjustable from 0 % to 100 % (100 % carrier level is proportional to one
half of the programmed amplitude level)
Resolution: 3 digits (100 counts max)
Distortion: <1 % at 70 % modulation (Measured with Fc = 1 MHz and Fm = 1 KHz)
Modulating Signal:
Bandwidth: DC to 500 KHz (DC coupled)
Sensitivity: 0 V to 2.5 Vp-p produces 0 % to 100 % modulations respectively when carrier is set to 100
%; 0 V to 5 Vp-p produces suppressed carrier amplitude modulation (SCAM)
having an output amplitude level of 0 V to 15 Vp-p into 50 ohms respectively
when carrier is set to 0 %
