28. Frequency Response
a. Performance Check
(1) Connect equipment as shown in figure 12.
(2) Position TI controls as listed in (a) through (d) below:
(a) FREQUENCY control to 0 MHz.
(b) BANDWIDTH switch to 300 kHz.
(c) SCAN WIDTH (red) switch to 0-1250 MHz.
(d) INPUT ATTENUATION switch to 20 dB.
(3) Set IF plug-in LOG/LINEAR switch to LINEAR and LINEAR SENSITIVITY
(LOG REF LEVEL) switch to 1 mV/DIV.
(4) Adjust signal generator frequency to 100 MHz and output level to produce a
7-division signal pip display. Note output level of signal generator.
(5) Slowly increase signal generator frequency to 500 MHz while maintaining
output level noted in (4) above. Note frequency which produces highest signal pip
amplitude.
(6) Adjust signal generator output level to produce an 8-division signal pip display
