b. Adjustments. No adjustments can be made.
23. Residual Response
a. Performance Check
(1) Position controls as listed in (a) through (h) below:
(a) FREQUENCY RANGE pushbutton to BANDS 1-3 (100 kHz-7.1 GHz).
(b) FREQUENCY SPAN/DIV control to 10 MHz.
(c) REFERENCE LEVEL control to -50 dBm.
(d) MIN RF ATTEN control to 0 dB.
(e) RESOLUTION BANDWIDTH control to 10 kHz.
(f) TIME/DIV switch to AUTO.
(g) VERTICAL DISPLAY 10 dB/DIV pushbutton to on.
(h) DIGITAL STORAGE (option 02) VIEW A/VIEW B pushbutton on.
(2) Scan the frequency range of bands 1, 2, or 3 in 100 MHz increments. Note
amplitude of any spurious response. Spurious amplitude must not exceed -100 dBm. (By
activating ΔF after each increment, it is easier to determine 100 MHz increments.)
b. Adjustments. No adjustments can be made.
24. Digital Storage
a. Performance Check
(1) Position controls as listed in (a) through (i) below:
(a) FREQUENCY control to 100 MHz.
(b) FREQUENCY SPAN/DIV control to 10 MHz.
