The pulse width range of the generator shall be from 5 to 9.99 ms, selectable in 1 nanoseconds increments. (2)Pulse width accu racy. The minimum pulse width accuracy shall be I1 ns plus time base

13、 stability). (c)Time base stability (1)Long term. The long term stability shall be better than 3xiO-/day 2 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-A-A-58037 (2)Temperature. The temperature stability shall be better than 1x1 O-*OC. (d)Inserion

14、 delay. A delay between an external trigger and an initial pulse shall not exceed 150 ns. (e)m. A jitter between an external trigger or an initial delay and the output pulse shall not exceed 250 picoseconds rms. (f)Trina. The trigger modes shall be manual, internal and external and be front panel se

15、lectable. (g)F,xternal trim. The pulse generator shall start to trigger when an input pulse, which has a minimum amplitude of 200 millivolts or less and a minimum pulse width of 1 O ns or less, is applied. The trigger shall be -2 to +2 volts, and have a positive, negative slope selection switch. (h)

16、kpetition rate. The maximum repetition rate of the pulse generator shall be at least 5 MHz. (i)bitial and de lay pulse ou ut. The pulse generator output shall be 5 volts into 50 ohms; the rise and fall time shall be less than 5 ns; selectable complements. (i)Internal clock modes . The clock shall op

17、erate from an internal oscillator that has a frequency of 5 or 10 KHz. (k)Remote operation. The generator shall be capable of remote operation with IEEE 488 interface bus. All front panel functions and controls except power, manual trigger and polarity shall be able to be initiated remotely via IEEE
