Return Loss ≥ 15 dB, 5 MHz–270 MHz Instrument switched on
Termination Detector
Triggers display symbol when
return loss of the signal path is
≤10 dB (approximates termina-
tion impedance of ≤37.5 Ω and
≥150 Ω).
Signal Amplitude Variable from 600 mV to 1000
mV in the following steps:
Coarse — 100 mV increments
on even 100 mV levels
Fine — 20 mV increments
Absolute accuracy
at 800 mV setting 800 ± 20 mV
Relative accuracy
Coarse increments
100 ± 8 mV From last 100 mV setting
Fine increments 20 ± 8 mV
DC Offset 0 ± 0.5 Volts
Rise and Fall Times 400–1000 ps 20% to 80% amplitude points
Jitter less than ± 360 ps over one line
