Tektronix 1L30 Instruction Manual page 4

Change information, if any, affecting this section will be found at the
rear of the manual.
The Type 1L30 Spectrum Analyzer described in this manu­
al is designed for use in Tektrohix oscilloscopes to display
the distribution of RF signals in the frequency range of
925 MHz to 10,500 MHz. The analyzer displays the fre­
quency distribution of the applied signal along the horizontal
axis .of the oscilloscope CRT and displays the signal energy
on the vertical axis.
The analyzer is designed for use in all Tektronix 530-,
540-, 550-, and 580-1 Series Oscilloscope. The analyzer plugs
directly into the oscilloscope and derives all its power from
'A Tektronix Type 81 Plug-In Adapter must be used with 580-Series
Oscilloscopes.

external Plug-In Unit Power Supply (such as the Tektronix
Type 127 and Type 132 Power Supplies) when provided
with a 100 volt sawtooth signal.
ambient temperature range of 0 °C to 50aC provided the
environmental ambient temperature has been stable for 4
hours and an initial warmup period of 20 minutes with
power applied is provided for the instrument to stabilize.
The performance check procedure given in Section 5 of
this manual provides a convenient method to check the
Operating requirements listed in this section.
