Quick Start: Learning How to Make Measurements
Analyzer Front Panel
9. ACTIVE CHANNEL keys. The analyzer has four independent display channels.
These keys allow you to select the active channel. Then any function you enter applies
to this active channel. Notice that the light next to the current active channel’s key is
illuminated.
10. The ENTRY block. This block includes the knob, the step keys, and the
number pad. These allow you to enter numerical data and control the markers.
You can use the numeric keypad to select digits, decimal points, and a minus sign for
numerical entries. You must also select a units terminator to complete value inputs.
11. INSTRUMENT STATE function block. These keys allow you to control
channel-independent system functions such as the following:
• copying, save/recall, and HP-IB controller mode
• limit testing
• external source mode
• tuned receiver mode
• frequency offset mode
• test sequence function
• harmonic measurements (Option 002)
• time domain transform (Option 010)
HP-IB STATUS indicators are also included in this block.
12. key. This key returns the instrument to either a known factory preset state, or
a user preset state that can be defined. Refer to the “Preset State and Memory
Allocation” chapter in the Reference Guide for a complete listing of the instrument
preset condition.
13. PROBE POWER connectors. These connectors (fused inside the instrument) supply
power to an active probe for in-circuit measurements of AC circuits.
14. R, A, and B connectors. These connectors allow you to apply input signals when
creating your own test setup. In addition, these connectors allow you to use the
HP 85046A/B, HP 85047A, or HP 85044A/B (discontinued) test sets to simplify
measurement setup.
15. RF OUT connector. This connects the RF output signal from the analyzer’s internal
source to a test set or power splitter.
