Agilent RF & Universal
Frequency Counter/Timers
Programming Comparison Guide
Technical Overview
53200 Series (53210A, 53220A, 53230A)
531xxA Series (53131A, 53132A, 53181A)
Introduction
The Agilent 53200 Series emula-
tion mode enables the Agilent
53131A, 53132A, 53181A (531xxA
Series) Standard Commands for
Programmable Instruments (SCPI)
command set to be used with a
53210A, 53220A, or 53230A (53200
Series) counter. This programming
comparison guide will list those areas
where 531xxA Series users might
find differences in operation when
using a 53200 Series counter. These
differences are few, but documented
in order to make it easier to verify
programs.
With 531xxA Series compatibility
mode selected, all programming is
through the counter’s remote inter-
face (LAN, USB, GPIB). The counter
display responds according to the
remote commands received. Pressing
any front panel key while in 531xxA
Series compatibility mode returns
the counter to 53200 Series mode
as prompted. Setting or changing to
either mode requires the instrument
to be restarted.
When the 531xxA compatibility mode
has been selected, most SCPI com-
mands should execute semantically
the same as the SCPI commands
described in the Agilent 53181A and
53131A/132A 225 MHz Universal
Counter Programming Guides avail-
able in the library section of each the
product’s web pages found at www.
/find/frequencycounters.
:CALCulate Subsystem
The 531xxA CALCulate1:IMMediate,
CALCulate1: IMMediate:AUTO,
CALCulate2: IMMediate, and
CALCulate2: IMMediate:AUTO com-
mands, which allowed recalculation
of old measurements, are not sup-
ported.
Measurement Instructions
The 531xxA READ?, FETCh?, and
MEASure? commands returned a
variable-length ASCII string whose
number of digits depended on the
actual measurement resolution. The
53200 Series will always return 15
digits.
The 531xxA READ:
FETch:
not allow data conversion from one
function to another.
must match the currently configured
measurement function.
:SENSe Subsytem – Trigger
events
Hysteresis
The 53200 series hardware has only
two input hysteresis levels, compared
to three on the 531xxA counters.
For 53131A/132A:
Sending the 53131A/132A
SENSe:EVENt{1|2}:HYSTeresis 50
or 100 command enables noise
rejection (INPut{1|2}:NREJect
ON) in the 53220A/230A;
SENSe:EVENt{1|2}:HYSTeresis 0
disables noise rejection.
For 53181A:
Sending the 53181A
SENSe:EVENt:HYSTeresis 50 or 100
command enables noise rejection
(INPut:NREJect ON) in the 53210A;
SENSe:EVENt:HYSTeresis 0 disables
noise rejection.

Reference Levels for pulse width and
duty cycle
The 53131A/132A allowed you to set
different reference levels for the ris-
ing and falling edges for pulse width
and duty cycle measurements using
the SENSe:EVENt{1|2}:LEVel subsys-
tem commands. The 53220A/230A
uses the same reference level for
both edges. If you require different
references levels for the two edges,
you can accomplish this by using the
time interval measurement function
instead of pulse width or duty cycle.
The 53131A/132A models allowed
the lower and upper reference values
for rise and fall time measurements
to be in different units (percent vs.
voltage). The 53220A/230A models
require the same units for both refer-
ence values (both must be percent, or
both must be voltage).
Gate Time Resolution
The 53131A/53132A had different
resolutions for long and short gate
times and delays for the following
commands:
CONFigure:TOTalize:TIMed
MEASure:TOTalize:TIMed?
SENSe:FREQuency:ARM:STOP:TIMer
SENSe:TINTerval:ARM:STOP:TIMer
SENSe:TINTerval:ARM:ESTOP:LAYer
1:TIMer
SENSe:TOTalize:ARM:STOP:TIMe
The resolution for gate time and delay
does not change based on value on
the 53220A/230A models.
The 53181A had different resolutions
for long and short gate times for the
SENSe:FREQuency:ARM:STOP:TIMer
command. The 53210A has the same,
better resolution regardless of the
gate time.
External Reference Signals
The 53181A & 53131A could auto-
matically adapt to external reference
signals of 1 MHz, 5 MHz, or 10 MHz.
The 53132A only accepted 10 MHz
signals. The SENSe:ROSCillator:E
XTernal:FREQuency? query would
measure and return which frequency
was present. The 53200 Series
accepts 1 MHz, 5 MHz, or 10 MHz,
but you need to specify via the SEN
Se:ROSCillator:EXTernal:FREQuency
command which frequency is present.
This command form is available in
53181A/53131A/53132A compatibil-
ity mode; the query form returns the
programmed value, not a measured
value.
The 53181A/53131A/53132A SENS
e:ROSCillator:EXTernal:CHECk com-
mand controlled whether the instru-
ment would detect and report errors if
the external reference signal was not
present at the end of a measurement.
The 53200 Series will always detect
this condition and report errors. The
531xxA command is accepted by the
53200 Series, but has no effect on the
instrument.
SCPI Macros
The 531xxA SCPI macro capabil-
ity is not supported in the 53200
Series, including the *DMC, *EMC,
*EMC?, *GMC?, *LMC?, *PMC,
MEMory:DELete:MACRo, and
MEMory:FREE:MACRo? commands.
RS-232 Commands
The 53200 Series does not include
an RS-232 port, and does not
support hard copy output. The
associated HCOPy:CONTinuous and
SYStem:COMMunicate:SERial subsys-
tem SCPI commands of the 531xxA
Series 53131A/132A are accepted by
the 53200 Series, but have no effect
on the instrument.
Diagnostics and Calibration
Due to significant hardware differenc-
es between the 53200 series and the
531xxA counters, the calibration pro-
cedure and some of the CALibration
subsystem commands are different.
The 531xxA DIAGnostic subsystem
commands are not supported.
Front Panel Operation
Given the complete redesign of the
front panel, the 531xxA SYSTem:KEY
and SYSTem:KEY:LOG? commands,
which simulate the pressing of a
front-panel key, are not supported.
Input Protection
When 50 ohm input impedance
is selected, the 531xxA and the
53200 Series specifications limit the
input voltage to 5 Vrms to prevent
damage to the input termination
resistor. If higher voltage is present,
53200 Series will automatically
switch the input impedance to 1
Mohm to prevent damage; the
531xxA counters do not have this
protection capability. If the automatic
protection is triggered on the 53200
Series, you will need to send the
53131A/132A INPut{1|2}:IMPedance
SCPI command to reset the input
impedance to 50 ohms (on 53181A:
INPut:IMPedance).

Reference Levels for pulse width and
duty cycle
The 53131A/132A allowed you to set
different reference levels for the ris-
ing and falling edges for pulse width
and duty cycle measurements using
the SENSe:EVENt{1|2}:LEVel subsys-
tem commands. The 53220A/230A
uses the same reference level for
both edges. If you require different
references levels for the two edges,
you can accomplish this by using the
time interval measurement function
instead of pulse width or duty cycle.
The 53131A/132A models allowed
the lower and upper reference values
for rise and fall time measurements
to be in different units (percent vs.
voltage). The 53220A/230A models
require the same units for both refer-
ence values (both must be percent, or
both must be voltage).
Gate Time Resolution
The 53131A/53132A had different
resolutions for long and short gate
times and delays for the following
commands:
CONFigure:TOTalize:TIMed
MEASure:TOTalize:TIMed?
SENSe:FREQuency:ARM:STOP:TIMer
SENSe:TINTerval:ARM:STOP:TIMer
SENSe:TINTerval:ARM:ESTOP:LAYer
1:TIMer
SENSe:TOTalize:ARM:STOP:TIMe
The resolution for gate time and delay
does not change based on value on
the 53220A/230A models.
The 53181A had different resolutions
for long and short gate times for the
SENSe:FREQuency:ARM:STOP:TIMer
command. The 53210A has the same,
better resolution regardless of the
gate time.
External Reference Signals
The 53181A & 53131A could auto-
matically adapt to external reference
signals of 1 MHz, 5 MHz, or 10 MHz.
The 53132A only accepted 10 MHz
signals. The SENSe:ROSCillator:E
XTernal:FREQuency? query would
measure and return which frequency
was present. The 53200 Series
accepts 1 MHz, 5 MHz, or 10 MHz,
but you need to specify via the SEN
Se:ROSCillator:EXTernal:FREQuency
command which frequency is present.
This command form is available in
53181A/53131A/53132A compatibil-
ity mode; the query form returns the
programmed value, not a measured
value.
The 53181A/53131A/53132A SENS
e:ROSCillator:EXTernal:CHECk com-
mand controlled whether the instru-
ment would detect and report errors if
the external reference signal was not
present at the end of a measurement.
The 53200 Series will always detect
this condition and report errors. The
531xxA command is accepted by the
53200 Series, but has no effect on the
instrument.
SCPI Macros
The 531xxA SCPI macro capabil-
ity is not supported in the 53200
Series, including the *DMC, *EMC,
*EMC?, *GMC?, *LMC?, *PMC,
MEMory:DELete:MACRo, and
MEMory:FREE:MACRo? commands.
RS-232 Commands
The 53200 Series does not include
an RS-232 port, and does not
support hard copy output. The
