Custom Low EMI PulseBlasterUSBTM
I. Low EMI PulseBlasterUSBTM
1. Overview
The Custom Low EMI PulseBlasterUSBTM is a low Electromagnetic Interference (EMI version of our
standard PulseBlasterUSBTM portable system. It measures 8” x 8.38” x 5.19” (20.32cm x 21.27cm x 13.18cm
and weighs 6.3 lbs (2.86 kg .The low EMI version includes the following features:
1.High performance, filtered AC power entry module.
2.Low-noise 3 A linear power supply.
3.Custom enclosure with enhanced shielding
4.TNC connectors for each output channel.
5.External clock input (1kHz to 50MHz .
6.Slowed slew rate of the output pulses.
7.Reduced 12 mA output current per channel.
8.8 Programmable Digital Output Bits (20ns resolution @ 50 MHz .
9.Automatic USB communication shutdown at frequencies lower than 50 MHz
2. Connector Information
This enclosure provides 8 output bits through TNC connectors, arranged as in Figure 1, below. There is also
an external clock signal input provided through a TNC connector. This clock line is terminated with a 50Ω
resistor.

The Trig/Res/Stat DB9 connector information is shown in Figure 2 and Table 1, below. The Hardware Trigger
and Hardware Reset are both active low, so each of these pins would need to be shorted to ground to cause
a trigger or reset, respectively.

3. Operation Instructions
Because this custom device needs to be able to operate at external clock frequencies down to 1 kHz, there
are instructions that you must follow in programming the device to output your desired pulse sequence. Keep
in mind that it is imperative that the clock input is 50MHz during programming.
1.Before you plug in the device, go to http:///www.spincore.com/support/spinapi and install the latest version
of our SpinAPI Driver Package.
2.Plug in your 50 MHz clock signal into 'Clock Input' TNC connector. The clock input line is terminated with
a 50Ω resistor, so you will need to use a 50Ω clock source. Also, the maximum clock signal that the
system can accept is 3.3V TTL. The minimum clock signal that the system can accept is 1.7V TTL.
3.Plug in USB cable into system and computer.
4.Insert power cord and turn on the power switch on the enclosure.
5.To use the system, program the device with whatever pulse program you choose. See the note below about
how to program the device. Make sure your clock input is 50 MHz during programming.
6.After programming, you may dial down 50 MHz signal to frequency of your choice, e.g. 1 kHz.
7.To reprogram with different pulse sequence, you need to change your clock source back to 50 MHz.
Note: Hardware trigger and reset do work at any frequency in the range (1 kHz - 50 MHz
