(Models 2620A and 2630)
21. ATTN. (ATTENUATOR). Output level attenuator
with four 10 dB attenuators which allow the signal
to be reduced prior to reaching the
OUTPUT jack.
The four attenuators are equal and each is activated
by depressing the button. When engaged, each
provides a 10 dB attenuation. Any combination of
buttons may be used to achieve the desired
attenuation.
22. OUTPUT. 50
Ω BNC output of the tracking
generator.
23. TRACK GEN. The tracking generator is activated
when this button is engaged. When activated, a sine
signal can be obtained at the OUTPUT BNC
connector at a frequency determined by the spectrum
analyzer. In ZERO SCAN mode, the center
frequency appears at the output.
24. LEVEL. This knob adjusts the level of the tracking
generator. Continuously variable from –10 dBm to
+l dBm; operates in conjunction with step
attenuators for +1 dBm to –50 dBm output level.
