N4951A/N4951B7 pattern generator remote head specifications (cont’d)
SJ1 frequency range
SJ modulation range
1 Hz to 150 MHz, over-programmable to 200 MHz
Range of SJ1 and SJ2. The maximum combined peak jitter of SJ1 + SJ2 +RJ (p-p) + external jitter are
applied to the high frequency band modulator (see Figure 26).
0 to 0.8 UI p-p for modulation frequency 1 Hz to 30 MHz, 4 to 32 Gb/s
0 to 0.33 UI p-p for modulation frequency >30 MHz to 150 MHz, 4 to 29 Gb/s
0 to 0.2 UI p-p for modulation frequency >30 MHz to 150 MHz, >29 to 31.5 Gb/s
Over-programmable to 1.0 UI
RJ1 modulation range
0 to 24 mUI rms, 4 to 29 Gb/s
0 to 14 mUI rms, >29 to 31.5 Gb/s
Over-programmable to 50 mUI rms
0.002 to 100 UI for frequency ≤ 62.5 kHz
Low frequency PJ1 modulation range
0.002 to (6.25E6/ PJ frequency) for frequency > 62.5 kHz to 17 MHz (see Figure 26)
0.001 to 50 UI for frequency ≤ 68.4 kHz
Low frequency external modulation
range
0.001 to (3.42E6/modulation frequency) for frequency > 68.4 kHz to 4 MHz (see Figure 26)
