TDS 500C, TDS 600B & TDS 700C Supplement 1
Introduction
This document contains three supplements to the TDS 500C, TDS 600B, and
TDS 700C manuals:
TDS 580C Supplement provides information that extends the TDS 500C,
TDS 600B, and TDS 700C manuals to cover a new oscilloscope model, the
TDS 580C Digitizing Oscilloscope. See page 3.
Version 5.2 Firmware Supplement provides information that extends the
manuals to cover the new or changed functions that are available in the
TDS 500C and TDS 700C oscilloscopes, starting with firmware version 5.2.
See page 5.
Option 1G Supplement provides information that extends the manuals to
cover two oscilloscope models, the TDS 540C and TDS 754C Option 1G
Oscilloscopes. See page 29.
Introduction
2TDS 500C, TDS 600B & TDS 700C Supplement
TDS 500C, TDS 600B & TDS 700C Supplement 3
TDS 580C Supplement
The TDS 500C, TDS 600B, and TDS 700C model oscilloscope manuals also
cover an oscilloscope model that is not mentioned in those manuals, the
TDS 580C.
This supplement lists the differences between the TDS 580C and the TDS 784C,
which is the model that the TDS 580C is most like.
Except for the differences shown in the table below, The TDS 580C is identical
to a TDS 784C. Most of the information in your user manual (and other TDS
documents) that applies to the TDS 784C, also applies to the TDS 580C.
Like the TDS 784C, the TDS 580C provides four full-function channels,
digitizing rates to 4 GS/second, a 1 GHz analog bandwidth, and up to 50 K
record lengths (or longer with options 1M or 2M). The table below lists the key
areas where the TDS 784C and the 580C differ:
Feature 784C 580C
Display Color Monochrome
FFT Yes Optional(2F)
RS232 and Centronics Port Yes Optional(13)
Accessory Pouch Standard Available
(016-1268-00)
All options listed for the TDS 784C are available for the TDS 580C. The
TDS 784C, and the TDS 580C ships without probes. The probe options are:
Option 24. Add four P6139A passive oscilloscope probes.
Option 26. Add four P6245 1.5 GHz FET oscilloscope probes.
The option 1G, detailed in Option 1G Supplement in this document, is not
available for the TDS 580C.
The TDS 580C comes with the firmware features listed in Version 5.2 Firmware
Supplement in this document; no upgrade is required. See page 5.

If on, mask pass/fail testing displays the results in the Pass/Fail Testing side
menu. To start mask pass/fail testing, press MEASURE ➞Measure (main) ➞
Masks (pop-up) ➞Mask Counting (main). Then toggle Pass/Fail Test (side) to
On.
The Pass/Fail Test side menu displays the testing status:
Passing is displayed if, for the requested number of acquired waveforms, the
number of hits does not exceed the number of hits specified in the failure
threshold
Failed is displayed if there are hits greater than or equal to the Pass/Fail
Failure Threshold in the masks in the requested number of acquired
waveforms
OFF Passed or OFF Failed is displayed when the test is complete, based on
the result of the test
Pass/fail testing turns on mask counting and resets the mask count to 0.
Hits greater than or equal to the Pass/Fail Failure Threshold are a test failure. To
set the threshold, press MEASURE ➞Measure (main) ➞Masks (pop-up) ➞
Mask Counting (main) ➞Pass/Fail Failure Threshold (side). Then use the
general purpose knob or keypad to set the failure threshold.

The test continues until the minimum number of waveforms has been acquired.
To set the minimum number of waveforms, press MEASURE ➞Mea-
sure (main) ➞Masks (pop-up) ➞Mask Counting (main) ➞Set Minimum
Number of Waveforms (side). Then use the general purpose knob or keypad to
set the number of waveforms.
The Pass/Fail Bell menu controls whether the mask pass/fail test rings a bell. To
control the Pass/Fail Bell, press MEASURE ➞Measure (main) ➞Masks
(pop-up) ➞Mask Counting (main). Then toggle Pass/Fail Bell (side) to Off,
On Failed, or On Completion.
Off does not ring a bell
On Completion rings the bell when the test is complete
On Failed rings the bell when a failure is detected and when the test is
complete
Use the procedures in your manual. Also, if a user mask is active, Autoset
adjusts the selected trace to match the last standard mask selected, if possible.
Use the HORIZONTAL POSITION control or the Time Base Position menu to
manually align the waveform to a mask. Adjusting the HORIZONTAL POSI-
TION resets mask counting.
Use Mask Margins to determine if your signal passes with a specific margin. To
set a mask margin do the following steps:
1. To enable mask margins, press MEASURE ➞Measure (main) ➞Masks
(pop-up) ➞Mask Margins (main). Then toggle Mask Margins (side) to
On or Off. If a user defined mask has more than three masks, turning on
mask margins will generate an error. Turning Mask Margins off will set the
Margin Percentage to 0%.
2. To set the margin percentage, press Margin Percentage (side). Then use the
general purpose knob or the keypad to set the percentage. Mask margin
percentage moves the mask boundaries to reflect the selected margin.
Negative margins make it easier to pass a mask test.
Set mask options to determine which waveform the masks are compared against,
to turn masks on or off, to enable Autoset to a mask, to enable offset adjustment
to masks, and to enable the digital waveform filter (see Figure NO TAG).
To select the channel that is compared against the selected mask, press MEA-

toggle Mask Source (side) to Ch1, Ch2, Ch3, or Ch4. Mask Source is not
available in InstaVu II, because all on channels contribute to the mask.
To turn defined masks on or off, press MEASURE ➞Measure (main) ➞
Masks (pop-up) ➞Mask Options (main). Then toggle Mask Display (side)
ON or OFF.
To invert a DS1, DS1A, DS1C, DS2, DS3, E1 Sym, E1 Coax, E2, E3, STS-1,
STM1E, or E4 mask, press MEASURE ➞Measure (main) ➞Masks
(pop-up) ➞Mask Options (main). Then toggle Invert Mask (side) ON or OFF.
When ON and you select one of the above masks, the created mask is for a pulse
of opposite polarity to that of the standard mask.

NOTE. If you select Manual, some controls are automatically adjusted; if you
select Auto, a complete Autoset is performed. Also, if a user mask is active,
Autoset adjusts the selected trace to match the last standard mask selected, if
possible.
To control whether an autoset is performed when a standard mask is selected,
press MEASURE ➞Measure (main) ➞Masks (pop-up) ➞Mask Op-
tions (main). Then toggle Std Mask Autoset (side) to Auto or Manual.
