Adjust HM5010/5011 to basic setting (see above). Apply input signal of 100MHz, level +7dBm
Overriding the input allows for the harmonics of the input signal to become visible (fig. 7)
simplifies the adjustment of individual spectral lines in horizontal direction.
adjust:
Spectral line at 400MHz
Turn X-ampl. knob on front of instrument to have the 4 spectral lines matched with
the corresponding graticule lines on the screen(fig. 8
adjust:
Spectral line at 100MHz
With Trimpot RV171 align to match this spectral line with the corresponding
graticule line on the screen (fig. 9
adjust:
Zero Peak
With Trimpot RV173 align to match this spectral line with the corresponding
graticule line on the screen (fig. 9
adjust:
Spectral line at 600-1000MHz
With Trimpot RV186 adjust to match 700MHz to the correct graticule line.
adjust:
Spectral line at 800 MHz;
With Trimpots RV181 + RV183 for 900MHz and RV197 for 1000MHz (PIC 3)
adjust to match this spectral line with the corresponding graticule line on the
screen.
adjust:
Beam length
With Trimpot RV101 adjust beam to end approx. 1mm beyond the right CRT
boundary (graticule) (Fig. 11
