16, numbered 0-15.
HP 54620-61801 with channels grouped in
two sets of 8. Instrument is compatible with
16-channel HP 1650-61607 cable and
accessories.
~100 k Ω and 8 pF.
± 40 Volts peak.
± 10V about threshold.
500 mV peak-to-peak about threshold.
To meet timing accuracy, the threshold
value must be within 20% of the 50% value
of the input signal.
Threshold levels can be assigned to the
input channels in groups of 8 channels (0-7
and 8-15) and external trigger.
± 6.0 Volts.

TTL = 1.5 V.
CMOS = 2.5 V.
ECL = –1.3 V.
2.0 ns typical.
3.0 ns maximum.
