TB 9-6625-1176-24
IDENTIFICATION AND DESCRIPTION
1. Test Instrument Identification.
This bulletin provides instructions for the
calibration of Pulse Generator, Hewlett-Packard, Model 214B. The manufacturer's manual
was used as the prime data sources in compiling these instructions. The equipment being
calibrated will be referred to as the TI (test instrument) throughout this bulletin.
a. Model Variations. None.
b. Time and Technique. The time required for this calibration is approximately 4
hours, using the dc and low frequency technique.
2. Forms, Records, and Reports
a. Forms, records, and reports required for calibration personnel at all levels are
prescribed by TB 750-25.
b. Adjustments to be reported are designated (R) at the end of the sentence in which
they appear. When adjustments are in tables, the (R) follows the designated adjustment.
Report only those adjustments made and designated with (R).
3. Calibration Description. TI parameters and performance specifications which
pertain to this calibration are listed in table 1.
Table 1. Calibration Description
Test instrument parameters
Performance specifications
Repetition rate
Range: Repetition rate 10 Hz to 10 MHz in six
decade ranges. In 30 to 100 V
amplitude range, maximum repetition
rate is 4 MHz. Calibrated vernier provide
continuous adjustment within ranges
Accuracy: (10% of setting + 1% of FS)
Pulse width
Range: 25 ns to 10 ms in 6 decade ranges;
continuously adjustable by vernier
Accuracy: (10% of setting + 1% of FS + 5 ns)
Duty cycle
10% for 30 to 100 V amplitude range
50% for all other ranges (maximum 10 ms width)
Transition times
Accuracy: 15 ns for leading and trailing edges
Preshoot, overshoot, and ringing
Accuracy: +5% of pulse amplitude
Pulse polarity
Positive or negative, switch selectable
Pulse delay
Pulse can be delayed with respect to trigger
output from +10 ns ( + fixed delay) to +10 ms
in 5 decade ranges (fixed delay is 50 10 ns)
Accuracy: (10% of setting + 1% of FS) + fixed
delay (fixed delay is 50 10 ns)
Pulse advance
Pulse can be advanced with respect to trigger
output from +10 ns ( - fixed delay) to +10 ms
in 5 decade ranges (fixed delay is 50 10 ns)
Accuracy: (10% of setting + 1% of FS) + fixed
delay (fixed delay is 50 10 ns)
