Single Shot Mode

During Single Shot operation, one pulse is generated each time the Run key is pressed. The rate at which pulses are produced is totally dependent on how fast the Run key is pressed. The delay of each of the outputs is relative to To (the internal clock).

Channel Menus

This set of menus is used to set enable and set the current, delay, pulse width for each of the output channels.

n:Enable - Tn:Enable

Each of the two (2) channels has independent output control and may be enabled or disabled from the n:Enable menu, where n = 1, 2. When disabled, the channel will not generate a current pulse when the unit is triggered.

n:Iamps - Tn:Iamps

Each of the two (2) channels has an independent output current setting from the

n:Iamps menu where n = 1, 2. Currents from 00.00 to 25.00A may be selected with a resolution of 10mA. Current is provided from a 3,700mF capacitor bank, which is charged to nominally 44V. The maximum current available will therefore be limited to the bank voltage and the load resistance. (The capacitor bank is charged by an isolated power supply which is current limited and thus takes approximately 15 seconds to charge.) The charge ready LED indicator illuminates when the capacitor bank is fully charged.

n:Dly - Tn :Delay

Each of the two (2) channels has an independent delay setting which is set from the Tn:Dly menu, where n = 1, 2. Delays from 0 to 99.999999 seconds may be selected with a resolution of 200ns.

When in any mode but External Trigger, the Delay setting sets the delay from the time the internal timer To goes high until a pulse is output on a particular channel.

When in External Trigger mode, the delays are with respect to the active edge of the external trigger input signal.
