Input and Output 
Connectors
The Model 301/302 has 6 or 9 BNC connectors on its front panel: one 
main output and one auxiliary output per channel, one SYNC output, 
one AM input per channel, one trigger input and one sample clock 
input. 
Main Output - 
Channel A 
The channel A output connector outputs fixed (standard) waveforms 
to 150 MHz, user (arbitrary) and sequenced waveforms with sampling 
clock to 300 MS/s. Output impedance is 50Ω, that is, the cable 
connected to this output should be terminated with 50Ω. Output 
amplitude accuracy is calibrated when connected to a 50Ω load. The 
output amplitude is doubled when the output impedance is above 1 
MΩ. 
Auxiliary Output - 
Channel A (I) 
The Auxiliary output connector outputs exactly the same waveforms 
as the Main output connector. The only difference is that the low 
output has fixed amplitude of 1 Vp-p into 50Ω 
Main Output - 
Channel B 
The Channel B output connector outputs fixed (standard) waveforms 
to 150 MHz, user (arbitrary) and sequenced waveforms with sampling 
clock to 300 MS/s. Output impedance is 50Ω, that is, the cable 
connected to this output should be terminated with 50Ω. Output 
amplitude accuracy is calibrated when connected to a 50Ω load. The 
output amplitude is doubled when the output impedance is above 1 
MΩ. 
Auxiliary Output - 
Channel B (Q) 
The Channel B Auxiliary output connector outputs exactly the same 
waveforms as the Main output connector. The only difference is that 
the low output has fixed amplitude of 1 Vp-p into 50Ω 
SYNC Output 
The SYNC output generates a single TTL pulse for synchronizing 
other instruments (i.e., an oscilloscope) to the output waveform. The 
SYNC signal always appears at a fixed point relative to the waveform. 
The location of the signal along the waveform is programmable. 
Trigger Input 
In general, the trigger input accepts signals that stimulate the output 
waveforms. The trigger input is inactive when the generator is in
