Options and Accessories
Options
75
Ω
Input Impedance (Option 1DP)
This option provides a 75
Ω
input impedance instead of the standard
50
Ω
impedance. Spectrum analyzers with this option use cables, circuit
boards, and front panels that are different from the standard units.
For Option 1DP, order E4411A 1DP.
Option 1DP is not retrofittable.
Tracking Generator (Option 1DN and
Option 1DQ)
Option 1DN (9 kHz to 1.5 GHz) and Option 1DQ (1 MHz to 1.5 GHz)
provide a built-in tracking generator. This source-receiver combination
makes insertion-loss, frequency response, and return-loss
measurements. The tracking generator has a wide distortion-free
dynamic range, plus good sensitivity and selectivity.
Option 1DN has the standard 50
Ω
output impedance. Option 1DQ has
a 75
Ω
output impedance, and is available only with Option 1DP.
For Option 1DN, order E4411A 1DN. For Option 1DQ, order E4411A
1DQ.
Options 1DN and 1DQ are also available as retrofit kits after the
purchase of your spectrum analyzer. Order E4411AU 1DN or E4411AU
1DQ.
IF, Sweep, and Video Inputs and Outputs
(Option A4J)
Option A4J provides the spectrum analyzer with inputs and outputs
typically found on most spectrum analyzers. They are as follows: SWP
OUT, HI SWP OUT (TTL), HI SWP IN (TTL), AUX VIDEO OUT, and
AUX IF OUT.
See “Rear Panel Features” in Chapter 2 for more information.
For Option A4J, order E4411A A4J.
Option A4J is also available as a retrofit kit after the purchase of your
spectrum analyzer. Order E4411AU A4J.
