TTI TG550 - Outputs; Inputs

Amplitude Modulation
Modulation Depth: Variable 0 to 100% typical.
Modulation Frequency: 400Hz internal. DC to 100kHz external.
External Modulation: By signal applied to COUNT/AM IN socket.
OUTPUTS
50Ω Main Out
Output Impedance:
50Ω.
Amplitude:
2mV to 20V peak-peak open circuit (1mV to 10V peak-peak into 50Ω) in
four switch-selectable ranges with 20dB vernier control within each
range.
Attenuator: 0, –20, – 40 or – 60dB.
DC Offset Range:
±10V. DC offset plus signal peak limited to ±10V (±5V into 50Ω); CLIP
shows in display when offset + signal peak exceeds ±10V. DC offset plus
waveform attenuated proportionally by the attenuator.
600Ω Main Out
Alternative output socket providing the same signal as the 50Ω Main Out but from 600Ω. The 50Ω
and 600Ω sockets are not independent.
Aux Out
Output Characteristics: Frequency, symmetry and phase the same as main outputs.
Output Level: 0 to 5V TTL/CMOS logic levels capable of driving 2 standard TTL loads.
Sweep Out
When internal sweep is selected the sweep signal is available as a 0 to 3V ramp from 600Ω.
INPUTS
Sweep In
The SWEEP IN/OUT socket is set to Sweep In when EXT SWEEP is selected.
Input Impedance:
10kΩ.
Input Sensitivity: 0 to 3V for 1000:1 sweep.
Maximum Allowable
Input Voltage: ± 10V.
Sweep Linearity: Better than 1%
Maximum Slew Rate of
Sweep Voltage: 0·1V/µs.
AM In
The AM/COUNT IN socket is set to AM input when EXT AM is selected.
Input Impedance:
40kΩ.
Input Sensitivity: Approximately 2V peak-peak for 50% modulation.
Maximum Allowable
Input Voltage:
± 10V.
