HP 8753ET/ES supplemental characteristics (continued)
Trace functions
Display data
Display current measurement data, memory data, or current measurement with measurement and memory data simultaneously.
Trace math
Vector division or subtraction of current linear mea- surement values and memory data.
Display annotations
Start/stop, center/span, or CW frequency, source level, scale/div, reference level, marker data, softkey func- tions, warning and caution messages, trace identifica- tion, and pass/fail indication.
Autoscale
Automatically selects scale resolution and reference value to center the trace.
Electrical delay
Offset measured phase or group delay by a defined amount of electrical delay, in seconds.
Frequency blanking
Blank out all frequency information on the display. Requires an instrument preset to
Title
Add custom titles (49 characters maximum) to the dis- play.
Adjust display
Customize the color and brightness of the data traces, memory traces, reference lines, graticules, text, and warning messages. Default colors can be recalled along with one set of
Storage
Instrument state
Up to 31 instrument states can be stored internally or recalled via the SAVE/RECALL menu. Instrument states include all control settings, active limit lines, active list frequency tables, memory trace data, active calibration coefficients, and custom display titles. Storage is in nonvolatile memory.
Test sequences
Six measurement sequences can be stored or recalled via the sequencing menu. Sequences may also be recalled from Preset menu. Sequence register 6 is part of nonvolatile storage and is not erased during a power cycle. If sequence 6 is titled AUTO, it will be executed when power is turned on.
Disk drive
Data, instrument states, user graphics, data plots and test sequences can be stored on internal floppy disk in
Data hardcopy
Data plotting
Hardcopy plots are automatically produced with HP- GL compatible digital plotters. The HP 8753ET/ES pro- vides Centronics,
Data listings
Printouts of instrument data are directly produced with a printer such as the HP DeskJet or LaserJet. Select black & white or color print. For a list of compatible printers, consult our
Configure plots
Configure plots completely from the network analyzer by defining pen color and line type for data, text mark- ers, graticules, and memory traces.
Functions
Plot trace(s), graticule(s), marker(s), or text including operating and system parameters.
Quadrants
Plot entire display in one of four different quadrants of the plotter paper.
System capabilities
Limit lines
Define test limit lines that appear on the display for go/no go testing. Lines may be any combination of hor- izontal, sloping lines, or discrete data points.
External source mode
The receiver (input R) detects and
Automatic
The input signal frequency is counted and displayed.
Manual
Measures the input signal closest to the frequency specified by the user (within +0.5 to +5 MHz).
Tuned receiver
Tunes the receiver for a synthesized CW input signal at a precisely specified frequency. The time bases of the external RF source or sources must be tied to the external reference input (rear panel BNC). The built- in RF source is not used.
