Data Sheet
Resolution:
± ((150 ps rms + (1.4 x Trigger Error)) / (Sample Interval)
x Frequency
Accuracy: ± Resolution ± (Time Base Aging x Frequency)
Continuous Frequency Measurements (mean estimation)
rms Resolution (for number of measurements/block >3):
((square root of (13.5) x (150 ps rms + 1.4 x Trigger Error)) /
((# of Blocks)^1/2 x (# of Meas./Block)^3/2 x Sample Interval) x Freq.
Accuracy: ± Resolution ± (Time Base Aging x Frequency)
Time Interval Measurements
Least Significant Digit Displayed:
± ((200 ps) /( square root of (N)))
N = number of measurements averaged
Resolution: ± ((150 ps rms ± Start Trigger Error
± Stop Trigger Error) / (square root of (N)))
Accuracy: ± Resolution ± (Time Base Aging
x Time Interval)
± Trigger Level Timing Error
± 1 ns Systematic Error
(Systematic error can be reduced to <100 ps with the HP J06-59992A) Time Interval Calibrator)
Input: Channels A and B
The following refers to an 5372A with 54002A pods installed.
Range: dc to 500 MHz.
Sensitivity: (x1 attenuation, minimum hysteresis)
15 mV rms sine wave (45 mV pk-pk), typically 10 mV rms.
45 mV pk-pk for pulse input.
Hysteresis control is available to reduce input sensitivity to trigger noise.
Dynamic Range:
x1:45 mV pk-pk to 2 V pk-pk.
x2.5 attenuator: 115 mV pk-pk to 5 V pk-pk.
Minimum Pulse Width:
1 ns for all measurement modes except holdoff arming.
1.5 ns with holdoff arming.
Input: Channel C (option 030)
Type N Connector
Range: 100 MHz - 2 GHz (divide-by-4 prescaler).
Sensitivity: (0 dB attenuation)
100 MHz to 1.5 GHz: -25 dBm.
1.5 GHz to 2 GHz: -20 dBm.
Dynamic Range:
100 MHz to 1.5 GHz: -25 dBm to +7 dBm.
1.5 GHz to 2 GHz: -20 dBm to +7 dBm.
Trigger level fixed at 0V NOMINAL.
Impedance: ac coupled, 50 ohm, VSWR <2.5.
External Arm
Range: dc coupled to 100 MHz.
Minimum Pulse Width : 5 ns
Impedance: 1 Mohm NOMINAL, shunted by <50 pf.
Triggering adjustable in 20 mV steps
Range ±5.00 V
Measurement Control
Holdoff or Sample:
0 to 4 x 1e9 events (65,000 events with fast meas. mode); 2 ns to 8.0 seconds (131 usec with fast meas. mode).
Edge Holdoff or Sampling: HP 5372A becomes armed after a delay from edge as follows:
Ext Arm arms A or B <15 ns
B arms A, A arms B <8 ns
A arms A, B arms B <5 ns
Interval Sampling: 100 ns to 8 seconds (131 usec with fast meas. mode).
