PulseBlasterESR-PRO-II
Timing characteristics
The PulseBlasterESR-PRO-II contains an internal (on-board) 50 MHz crystal oscillator. This input
frequency is then internally multiplied by five yielding an internal (on-chip) frequency of 250 MHz. The
internal memory allows for pulse attributes to last up to 32.768 us in duration. The new control unit allows
pulse sequence attributes to be as small as one clock period, so as short as 4.0 ns. If shorter pulses are
needed, please contact SpinCore Technologies, Inc.
External triggering
PulseBlasterESR-PRO-II can be triggered externally via a dedicated hardware line. The latency of
the external trigger is one clock period. The hardware trigger is “active low” (triggered when external
trigger pin is grounded). The hardware trigger and hardware reset pins are pulled to 3.3 V via a 10 kΩ
resistor.
Summary
PulseBlasterESR-PRO-II is a versatile, multichannel, high-performance pulse/pattern TTL signal
generator. It can operate at speeds of up to 250 MHz, and is capable of generating pulse sequences with
attributes as short as 4.0 ns, with durations lasting up to 32.768 us. The device can output up to 8k
unique outputs. Its high-current output logic bits are independently controlled with an output voltage of
3.3 V (unterminated).
