Table 17 Input channels
Number of Channels 16, numbered 0-15.
Channel input cable HP 54620-61801 with channels grouped in
two sets of 8. Instrument is compatible with
16-channel HP 1650-61607 cable and
accessories.
Input R&C ~100 k Ω and 8 pF.
Maximum Input ± 40 Volts peak.
Dynamic range ± 10V about threshold.
Minimum input 500 mV peak-to-peak about threshold.
Minimum Input Voltage Overdrive To meet timing accuracy, the threshold
value must be within 20% of the 50% value
of the input signal.
Threshold Setting Threshold levels can be assigned to the
input channels in groups of 8 channels (0-7
and 8-15) and external trigger.
Threshold Range ± 6.0 Volts.
Threshold Accuracy
1
± (3% of setting ± 100 mV).
Preset threshold levels TTL = 1.5 V.
CMOS = 2.5 V.
ECL = –1.3 V.
Channel-to-Channel Skew 2.0 ns typical.
3.0 ns maximum.
