Maximum Allowable
Input Voltage:
Sweep In
The AM/FM IN socket can be used for EXT SWEEP when INPUT is set to FM.
Input Sensitivity:
Maximum Slew Rate of
Sweep Voltage:
AM In
The AM/FM IN socket is set for AM when INPUT is set to AM.
Modulation Depth:
Modulation Frequency:
Input Sensitivity:
Internal: linear or logarithmic; sweep Start and Stop frequencies set
with 3 digit resolution. Setting accuracy ± 10 digits.
External: linear.
10:1 within each range.
20ms to 1s in 10ms steps; 1s to 20s in 1s steps.
By signal applied to EXT SWEEP socket.
50Ω.
1V to 20V peak-peak in 100mV steps from 50Ω.
(0.5V to 10V into 50Ω).
± 10% of setting ± 1 step.
0dB, –20dB or –40dB.
± 10V in 100mV steps. DC offset plus signal peak limited to ± 10V
(± 5V into 50Ω). DC offset plus waveform attenuated proportionally by
the attenuator.
±10% of setting ± 1 step.
0 to 5V TTL/CMOS level capable of driving 4 standard TTL loads.
