Low-frequency Linearity
Bandwidth Limiter
0.1 division or less compression or expansion of
a two-division, center-screen signal when
positioned anywhere within the graticule area.
Reduces upper 3 dB bandpass to a limit of
13 MHz to 24 MHz.
a
lf instrument is subjected to "greater
than"
85% relative humidity, bandwidth is reduced by
50 MHz. After instrument is subjected to "greater
than"
85% relative humidity, it requires
more than 50 hours of operation at "less
than"
60% relative humidity before full bandwidth is
restored.
