Typical phase uncertainty for PHASE A rel B measurements
where channel B is 1.5 V RMS and channel A is varied in amplitude
NOTE: When sigrsa! B is smaller than signal A phase measurement uncertainty tends to be positive
Tl. and Tl? are times between 50% points of A and B as illustrated in the DEFINITIONS section.
Tl| error and Tlj error are the errors due to: 1 ) Trigger Level Timing Error, 2) Trigger Level Setting
Error, and 3) Trigger Error due to noise.
GATE TIME
Range: 100 ns to 10 7 s.
L.SD** Displayed: Up lo three digits with Ext.
Arm Enable OFF, 100 ns when ON. MIN Gate
Mode display zero.
NOTE: T ime displayed and actual gate time may
differ due to input signal synchronization
of gate.
TRIGGER LEVEL

X10, +50 to -50 volts.
Resolution: XI, 10 mV; X10, 100 mV.
Accuracy (XI): ± 20 mV, ± 0.5% of reading.
NOTE: Reading is center point of hysteresis
band. When in X 10. reading is multiplied by 10.

STATISTICS
Sample Si 2 e: Selectable between either N = 100
or N " 1000 samples.
Std. Dev.: Displays a standard deviation of
selected sample size.
Mean: Displays mean estimate of selected sample
size.
Smooth: Performs a weighted running average
and truncates unstable least significant digits
from display.
NOTE: Statistics functions performed after Math
functions.
MATH
All measurement functions, with exception of
GATE TIME and TRIG LVL, may be operated
upon by Math functions. Offset, Normalize, and
Scale may be used independently or together
as follows;
rv , Measurement + Offset _ ,
Display - r: --- x Scale.
Normalize
Numbers are entered via blue labeled keys.
DISABLE key will toggle off and on all active
math keys.
Number Value Range: ±1 x IQ - 9 to ± 9 * 10 9
Last Display: Causes value of previous display
to Offset (negative value). Normalize, or Scale
all subsequent measurements.
Measurement t-1: Causes each new measure¬
ment to be Offset {negative value), Normalized,
or Scaled by each immediately preceding
measurement.

GENERAL
Function Memory: Front panel settings for
Math, Statistics, Range Hold, Ext. Arm Enable,
Gate, and Cycle stored for current function
and immediately preceding function. GATE
TIME and TRIG LVL cio no! affect memory
Gate: Minimum, manual, or continuously variable
(NORM/FAST) via Gate Adj. control.
NORM: 20 ms to 4s NOMINAL,
FAST: 100 ps to 20 ms NOMINAL.
MIN: Minimum gate time. Actual time depends
on function. For FREQ A, (FREQ B),
FREQ C, and PER A, minimum gate = (one
period of input) x (prescale factor).
MANUAL: Each press opens or closes gate.
Cycle : Determines delay between measurements
NORM: No more than 4 readings per second
NOMINAL.
MIN: Updates display as rapidly as possible
("-IS readings per second, depending on
function}.
SINGLE: One measurement taken with each
press of button.
Arming: Ext. Arm Enable key allows rear panel
input to determine Start and/or Stop point of
a measurement. External gate defined by both
Start and Stop armed. All measurements are
armabie except Manual Totalize, Phase, and
Trigger Level.
Start Arm: + or - slope of arm input signal
starts measurement.
Stop Arm: + or - slope of arm input signal
stops measurement- When used, Start arm
must occur before Stop arm.
Ext. Arm Input: Rear panel BNC accpts TTL
into 20 kfl.
Minimum Start to Stop Time: 200 ns.
Trigger Level Out: DC output into 1 Mil via
rear panel BNC’s for Channel A and B; not
adjusted for attenuators.
Accuracy at DC (XI): ± 15 mV ± 0.5% of
TRIG LVL reading.
Gate Out: TTL level into 1 kfl; goes low when
gate open; rear pane! BNC.
Range Hold: Freezes decimal point and
exponent of display.
Reset: Starts a new measurement cycle when
pressed.
Check: Performs internal self test and lamp test.
Display: 12 digit LED display in engineering
format; exponent range of + i 8 to -18.
Overflow: Ail measurements which would
theoretically cause a display of more than 12
digits wiil display 12 most significant digits.
Operating Temperature; 0 to 50°C.
Power Requirements: 100 . 120, 220 , 240 VAC
(+5%, -10%), 48-66 Hz, 130 VA max.
Weight: Net, 8.8 kg (19 lbs. 8 oz ); shipping,
13.6 kg (30 lbs.).
